Add wallpaper, power, date, accessibility, and real search
Continues the settings expansion toward replacing GNOME Settings for everything Panama actually owns. Wallpaper. A thumbnail grid rather than a path field: the value of this setting is the picture, so typing a path to something you cannot see is the worst version of it. Two things about hyprpaper 0.8 shaped this. Its IPC is much smaller than older documentation suggests -- preload, listloaded, unload, and reload all answer "invalid hyprpaper request", so setting is a single call with no preload. And the "<empty>,<path>" form that used to mean every output is silently ignored, so a wallpaper set that way appears to succeed and never changes; outputs are walked explicitly instead. hyprpaper.conf lives in the repo through the ~/.config/hypr symlink and so cannot hold machine state, which is why the choice lives in the shared settings store and is re-applied at startup. Power & Lock. hypridle has no IPC for reconfiguration and its config is hyprlang rather than the shared JSON, so scripts/panama-idle generates a config from the settings store and restarts the daemon. The generated file lives under XDG_STATE_HOME for the same symlink reason, with a systemd drop-in pointing hypridle at it. Management is a real state and the page says which one you are in rather than showing sliders that quietly do nothing. Zero means never for all three timers, which a naive template would render as "immediately". Date & Time. Deliberately not stored in Panama's settings: the timezone and network time belong to the machine and are shared with sessions that never see this file. Storing a copy would create a second answer to a question the system already answers. Reads and writes timedatectl directly; a cancelled polkit prompt surfaces as an error rather than as a value that appears to have been accepted. Accessibility. Pointer size and text scale have to agree across three consumers with no shared configuration -- the compositor, GTK, and the shell -- so the store is the source of truth and the values are pushed outward to gsettings and hyprctl setcursor. Search now indexes the schema instead of the twelve page labels. "gaps", "wallpaper", and "screenshot" previously found nothing on an app that has all three, which is the clearest way a settings app feels smaller than it is. Shortcuts are indexed by what they do. A contract asserts every non-internal schema label is reachable, so a new setting cannot be added in an undiscoverable state. The GNOME delegation allow-list was widened to the panel names gnome-control-center actually reports; the previous list contained "users", which is not one of them and so opened nothing.

// knowing about hyprpaper 0.8:
|

//
|

// * Its IPC is much smaller than the documentation for older versions
|
||||
// suggests. `wallpaper <output>,<path>` and `listactive` work; `preload`,
|
||||
// `listloaded`, `unload`, and `reload` all answer "invalid hyprpaper
|
||||
// request". So there is no preload step -- setting is a single call.
|
||||
// * hyprpaper.conf lives in the Panama repo via the ~/.config/hypr symlink,
|
||||
// so it cannot be rewritten at runtime without dirtying a tracked file.
|

// The chosen wallpaper therefore lives in the shared settings store like

// every other preference, and is re-applied when the shell starts.
