* feat(settings): add option to suppress config reload toast (#2730)
Add a toggle in Settings → Compositor Layout to disable the 'config reloaded' toast for Niri and MangoWC compositors. Session setting showConfigReloadToast defaults to true.
* chore: update settings search index for config reload toast
* refactor(settings): rename 'Compositor Notifications' to 'Compositor Toasts'
* fix(settings): reuse existing I18n.tr('Notifications') translation
Since Mango v0.15.0, disable_monitor sets only_sleep=0 which removes the
output from the layout entirely. On NVIDIA (proprietary driver), the DRM
handshake fails on re-enable, leaving a black screen recoverable only via
TTY switch.
sleep_monitor/wakeup_monitor set only_sleep=1, keeping the output in the
layout while powered off. This matches the pre-v0.15 behavior and fixes
DPMS wake on NVIDIA.
These commands are available since Mango v0.15.0 (commit b0326d7).
