* Add hotspot contract layer with capability-gated dispatch.
Establish the interface and manager plumbing for hotspot support so backends can opt in without expanding the core Backend contract.
Only backends that implement HotspotBackend get hotspot state propagated; others are forced to unsupported regardless of what they self-report.
* Add IPC handlers and API docs for hotspot actions.
Wire up configure/ start/ stop hotspot through the request router so the QML service layer can drive hotspot operations.
Bump API version to 27 and document the capability-gating contract clients should follow.
* Implement NetworkManager hotspot backend.
Implement HotspotBackend on NetworkManagerBackend with DMS-owned profile management, AP capability detection, and band validation.
Device resolution is deferred to StartHotspot when no device is specified, so profiles survive hardware changes.
* Isolate client Wi-Fi state from AP-mode connections.
Filter AP-mode profiles and access points out of all client Wi-Fi paths so the DMS hotspot (and user-created APs) never appear as saved networks, visible networks, or connected state.
This protects existing client behavior before hotspot controls are exposed in the UI.
* Prefer idle radios for automatic hotspot device selection.
* Add hotspot properties and methods to QML service layer.
Expose hotspot state and actions through DMSNetworkService, NetworkService, and LegacyNetworkService.
Capability is gated on API version and backend-reported support, not backend name checks, and stays stable when Wi-Fi radio is disabled.
* Add hotspot controls to Settings and Control Center.
Settings shows a hotspot setup card as a sibling in the Wi-Fi tab with SSID, password, device, band, save, and start/ stop controls.
Control Center shows a compact row that toggles a configured hotspot or routes to Settings for initial setup.
Both stay visible when Wi-Fi is disabled, explaining the requirement instead of hiding.
* Add translator context to hotspot strings.
Pulses the WiFi and Bluetooth status icons while a connection is in
progress (lock screen, DankBar control center button, control center
compound pill). The pulse is implemented as a reusable Widgets/DankBlink
component, and the wifi-connecting condition is centralized as
NetworkService.isWifiConnecting.
