notifications(Settings): Update notifs popout settings overflow

Fixed a QML property binding timing issue where dynamically created timers
and processes for per-monitor wallpaper cycling were being assigned to
properties and then immediately read back, which could return undefined
or stale values.

The fix stores the created object in a local variable before assigning
to the property map, ensuring a valid reference is always used.

Affected functions:
- startMonitorCycling() - timer creation
- cycleToNextWallpaper() - process creation
- cycleToPrevWallpaper() - process creation

+
+          ## Requirements
+
+          - Wayland compositor (niri or Hyprland recommended)
+          - Quickshell framework
+          - Qt6
+
+          ## Installation Steps
+
+          1. **Install quickshell assets:**
+             ```bash
+             mkdir -p ~/.config/quickshell
+             cp -r dms ~/.config/quickshell/
+             ```
+
+          2. **Install the DMS CLI binaries:**
+             ```bash
+             sudo install -m 755 bin/dms /usr/local/bin/dms
+             ```
+
+          3. **Install shell completions (optional):**
+             ```bash
+             # Bash
+             sudo install -m 644 completions/completion.bash /usr/share/bash-completion/completions/dms
+
+             # Fish
+             sudo install -m 644 completions/completion.fish /usr/share/fish/vendor_completions.d/dms.fish
+
+             # Zsh
+             sudo install -m 644 completions/completion.zsh /usr/share/zsh/site-functions/_dms
+             ```
+
+          4. **Start the shell:**
+             ```bash
+             dms run
+             ```
+
+          ## Configuration
+
+          - Settings are stored in `~/.config/DankMaterialShell/settings.json`
+          - Plugins go in `~/.config/DankMaterialShell/plugins/`
+          - See the documentation in the `dms/` directory for more details
+
+          ## Troubleshooting
+
+          - Run with verbose output: `DMS_LOG_LEVEL=debug dms run`
+          - Ensure all dependencies are installed

+# Contributing
+
+Contributions are welcome and encouraged.
+
+To contribute fork this repository, make your changes, and open a pull request.
+
+## Setup
+
+Install [prek](https://prek.j178.dev/) then activate pre-commit hooks:
+
+```bash
+prek install
+```
+
+### Nix Development Shell
+
+If you have Nix installed with flakes enabled, you can use the provided development shell which includes all necessary dependencies:
+
+```bash
+nix develop
+```
+
+This will provide:
+
+- Go 1.25+ toolchain (go, gopls, delve, go-tools) and GNU Make
+- Quickshell and required QML packages
+- Properly configured QML2_IMPORT_PATH
+
+The dev shell automatically creates the `.qmlls.ini` file in the `quickshell/` directory.
+
+## VSCode Setup
+
+This is a monorepo, the easiest thing to do is to open an editor in either `quickshell`, `core`, or both depending on which part of the project you are working on.
+
+### QML (`quickshell` directory)
+
+1. Install the [QML Extension](https://doc.qt.io/vscodeext/)
+2. Configure `ctrl+shift+p` -> user preferences (json) with qmlls path
+
+**Note:** Paths may vary by distribution. Below are examples for Arch Linux and Fedora.
+
+**Arch Linux:**
+
+```json
+{
+  "[qml]": {
+    "editor.defaultFormatter": "qt-project.qmlls",
+    "editor.formatOnSave": true
+  },
+  "qt-qml.doNotAskForQmllsDownload": true,
+  "qt-qml.qmlls.customExePath": "/usr/lib/qt6/bin/qmlls",
+  "qt-core.additionalQtPaths": [
+    {
+      "name": "Qt-6.x-linux-g++",
+      "path": "/usr/bin/qmake"
+    }
+  ]
+}
+```
+
+**Fedora:**
+
+```json
+{
+  "[qml]": {
+    "editor.defaultFormatter": "qt-project.qmlls",
+    "editor.formatOnSave": true
+  },
+  "qt-qml.doNotAskForQmllsDownload": true,
+  "qt-qml.qmlls.customExePath": "/usr/bin/qmlls",
+  "qt-core.additionalQtPaths": [
+    {
+      "name": "Qt-6.x-Fedora-linux-g++",
+      "path": "/usr/bin/qmake6"
+    }
+  ]
+}
+```
+
+3. Create empty `.qmlls.ini` file in `quickshell/` directory
+
+```bash
+cd quickshell
+touch .qmlls.ini
+```
+
+4. Restart dms to generate the `.qmlls.ini` file
+
+5. Make your changes, test, and open a pull request.
+
+### I18n/Localization
+
+When adding user-facing strings, ensure they are wrapped in `I18n.tr()` with context, for example.
+
+```qml
+import qs.Common
+
+Text {
+  text: I18n.tr("Hello World", "<This is context for the translators, example> Hello world greeting that appears on the lock screen")
+}
+```
+
+Preferably, try to keep new terms to a minimum and re-use existing terms where possible. See `quickshell/translations/en.json` for the list of existing terms. (This isn't always possible obviously, but instead of using `Auto-connect` you would use `Autoconnect` since it's already translated)
+
+### GO (`core` directory)
+
+1. Install the [Go Extension](https://code.visualstudio.com/docs/languages/go)
+2. Ensure code is formatted with `make fmt`
+3. Add appropriate test coverage and ensure tests pass with `make test`
+4. Run `go mod tidy`
+5. Open pull request
+
+## Pull request
+
+Include screenshots/video if applicable in your pull request if applicable, to visualize what your change is affecting.

+
+DankMaterialShell is a complete desktop shell for [niri](https://github.com/YaLTeR/niri), [Hyprland](https://hyprland.org/), [MangoWC](https://github.com/DreamMaoMao/mangowc), [Sway](https://swaywm.org), [labwc](https://labwc.github.io/), [Scroll](https://github.com/dawsers/scroll), [Miracle WM](https://github.com/miracle-wm-org/miracle-wm), and other Wayland compositors. It replaces waybar, swaylock, swayidle, mako, fuzzel, polkit, and everything else you'd normally stitch together to make a desktop.

+
+**System Monitoring**
+Real-time CPU, RAM, GPU metrics and temperatures with [dgop](https://github.com/AvengeMedia/dgop). Process list with search and management.
+
+**Powerful Launcher**
+Spotlight-style search for applications, files ([dsearch](https://github.com/AvengeMedia/danksearch)), emojis, running windows, calculator, and commands. Extensible with plugins.
+
+**Control Center**
+Unified interface for network, Bluetooth, audio devices, display settings, and night mode.
+
+**Smart Notifications**
+Notification center with grouping, rich text support, and keyboard navigation.
+
+**Media Integration**

+# DMS Backend & CLI
+
+Go-based backend for DankMaterialShell providing system integration, IPC, and installation tools.
+
+**See [root README](../README.md) for project overview and installation.**
+
+## Components
+
+**dms CLI**
+Command-line interface and daemon for shell management and system control.
+
+**dankinstall**
+Distribution-aware installer with TUI for deploying DMS and compositor configurations on Arch, Fedora, Debian, Ubuntu, openSUSE, and Gentoo.
+
+## System Integration
+
+### Wayland Protocols (Client)
+
+All Wayland protocols are consumed as a client - connecting to the compositor.
+
+| Protocol                                  | Purpose                                                     |

+
+### Plugin System
+
+- Plugin registry integration
+- Plugin lifecycle management
+- Settings persistence
+
+## CLI Commands
+
+- `dms run [-d]` - Start shell (optionally as daemon)
+- `dms restart` / `dms kill` - Manage running processes
+- `dms ipc <command>` - Send IPC commands (toggle launcher, notifications, etc.)
+- `dms plugins [install|browse|search]` - Plugin management
+- `dms brightness [list|set]` - Control display/monitor brightness
+- `dms color pick` - Native color picker (see below)
+- `dms update` - Update DMS and dependencies (disabled in distro packages)
+- `dms greeter install` - Install greetd greeter (disabled in distro packages)
+
+### Color Picker
+
+Native Wayland color picker with magnifier, no external dependencies. Supports HiDPI and fractional scaling.
+
+```bash
+dms color pick              # Pick color, output hex
+dms color pick --rgb        # Output as RGB (255 128 64)
+dms color pick --hsv        # Output as HSV (24 75% 100%)
+dms color pick --json       # Output all formats as JSON
+dms color pick -a           # Auto-copy to clipboard
+```
+
+The on-screen preview displays the selected format. JSON output includes hex, RGB, HSL, HSV, and CMYK values.
+
+## Building
+
+Requires Go 1.25+
+
+**Development build:**
+
+```bash
+make              # Build dms CLI
+make dankinstall  # Build installer
+make test         # Run tests
+```
+
+**Distribution build:**
+
+```bash
+make dist         # Build without update/greeter features
+```
+
+Produces `bin/dms-linux-amd64` and `bin/dms-linux-arm64`
+
+**Installation:**
+
+```bash
+sudo make install  # Install to /usr/local/bin/dms
+```
+
+## Development
+
+**Setup pre-commit hooks:**
+
+```bash
+git config core.hooksPath .githooks
+```
+
+This runs gofmt, golangci-lint, tests, and builds before each commit when `core/` files are staged.
+
+**Regenerating Wayland Protocol Bindings:**
+
+```bash
+go install github.com/rajveermalviya/go-wayland/cmd/go-wayland-scanner@latest
+go-wayland-scanner -i internal/proto/xml/wlr-gamma-control-unstable-v1.xml \
+  -pkg wlr_gamma_control -o internal/proto/wlr_gamma_control/gamma_control.go
+```
+
+**Module Structure:**
+
+- `cmd/` - Binary entrypoints (dms, dankinstall)
+- `internal/distros/` - Distribution-specific installation logic
+- `internal/proto/` - Wayland protocol bindings
+- `pkg/` - Shared packages
+
+## Installation via dankinstall
+
+```bash
+curl -fsSL https://install.danklinux.com | sh
+```
+
+## Supported Distributions
+
+Arch, Fedora, Debian, Ubuntu, openSUSE, Gentoo (and derivatives)
+
+**Arch Linux**
+Uses `pacman` for system packages, builds AUR packages via `makepkg`, no AUR helper dependency.
+
+**Fedora**
+
+Uses COPR repositories (`avengemedia/danklinux`, `avengemedia/dms`).
+
+**Ubuntu**
+Requires PPA support. Most packages built from source (slow first install).
+
+**Debian**
+Debian 13+ (Trixie). niri only, no Hyprland support. Builds from source.
+
+**openSUSE**
+Most packages available in standard repos. Minimal building required.
+
+**Gentoo**
+Uses Portage with GURU overlay. Automatically configures USE flags. Variable success depending on system configuration.
+
+See installer output for distribution-specific details during installation.
