feat(finale): deliberation jury identity resolution, rankable projects, score-revision path, session sync

- submitVote resolves the caller's JuryGroupMember participant row server-side
  (was comparing JuryGroupMember id to User id — every juror got FORBIDDEN)
- getSessionWithVotes now includes category projects so the ranking form has
  data before finalize
- liveVoting.vote accepts any finale-ordered project (revision during
  deliberation); timed window still applies to the live project
- live.sendToScreens keeps LiveVotingSession.currentProjectId/status in sync
