fix(finale): live-verification fixes — session sync on start, honest vote form, reveal panel polish

Found by driving the full ceremony end-to-end in the browser:
- live.start + startPresentation sync LiveVotingSession (status/currentProjectId)
  — jury votes silently failed when the admin never used sendToScreens
- LiveVotingForm no longer shows 'submitted' on a failed mutation; pages
  re-key on votedAt so async vote data renders the right state after refresh
- reveal compose prefers DELIB_LOCKED deliberation results over jury score
  order (listSessions now includes results); Arm unlocks right after save
- deliberation jury page review cards re-key on revision
