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

+/**
+ * Deliberation jury wiring — regression for two launch blockers:
+ * 1. submitVote compared the JuryGroupMember id against User.id (FORBIDDEN for
+ *    every legitimate juror). The server now resolves the caller's participant
+ *    row itself; the client never sends an identity.
+ * 2. getSession had no project list before finalize (the ranking form rendered
+ *    empty). It now includes the round's projects filtered by session category.
