System-Tray: Quick-Access-Menü, Hide-on-Close, Cmd+Q beendet

Tray-Icon in der macOS-Menüleiste mit Linksklick zum Fokussieren und
Rechtsklick-Menü: Rapport öffnen, Dashboard, Zeiterfassung, Projekte,
Buchhaltung, Einstellungen, Beenden. Menü-Klicks senden ein
rapport:navigate-Event ans Frontend.

Der rote Schliessen-Button versteckt nur — die App läuft im Hintergrund
weiter. Cmd+Q (RunEvent::ExitRequested) und der Tray-Quit-Eintrag
setzen ein is_quitting-Flag und beenden die App wirklich.
