Refine crew column: names, Captain label, slide-out objectives

Follow-up tweaks to the scene dashboard:
- Bubbles now show the human player name alongside the Pi-Rat name.
- The Captain is named "Captain <name>" (the "Recruit" honorific swapped,
  or "Captain" prepended once Named) instead of a 🛞 icon — applied on
  bubbles and the character-sheet/duel headings via new crewLabel/
  captainName helpers in lib/cards.js.
- "Objectives" → "Crew Objectives" moved to the end of the roster as a
  left-aligned toggle with a right-aligned X/3 completed counter; it now
  slides the detailed list open in place (svelte/transition slide)
  instead of opening a modal.
