Wire CommandPalette/Provider into the frontend layout and add Cmd+K
hint in the SiteHeader. Register context-aware commands for banking,
helpdesk, mission RSVP, locker, shipments, and market pages.
Also removes the locker search's duplicate Cmd+K listener (now handled
globally), renames its button to 'Search Locker', and cleans up a
flappy page parenthetical.
