feat(ui): show and hide the Cockpit surfaces from a store

The Cockpit controller publishes which surfaces are shown (the entry
button and TR-3B chip, the HUD with its exit and reset buttons and
briefing card, and the Contact card) and the views bind them. Focus moves
to the exit button, and back to the entry, after Vue renders them.

Layout scheduling counts the published presence as visible, so entry
still lays out the cards. The Display portal restores only focus its move
dropped. The Missions layer no longer hides the Contact card directly.
