feat: add Cmd+K spotlight actions to all 23 apps

Each app's PillNavigation now has spotlightActions with app-specific
quick actions (create, navigate, settings). Users can press Cmd+K / Ctrl+K
from any app to search apps, navigate, and trigger actions.

Apps: todo, calendar, contacts, chat, picture, clock, zitare, cards,
storage, manacore, mukke, presi, context, questions, photos, planta,
citycorners, guides, calc, moodlit, matrix, uload, arcade
