refactor(awards): remove AWARD_MASTER role, fold features into jury chair flow

The AWARD_MASTER role split sponsor jurors into a parallel UI that hid
project files (only showed when the award was anchored to an evaluation
round) and duplicated the jury voting path with no real difference in
authority — tie-break and finalize were already governed by AwardJuror.isChair
regardless of the user's global role. Inviting a juror via the award page
defaulted to AWARD_MASTER, randomly fragmenting jury panels.

This collapses the role into JURY_MEMBER + isChair:

- specialAward.getMyAwardDetail now returns evaluation scores, chair
  visibility into other jurors' votes, and juror roster
- specialAward.submitVote accepts an optional justification per vote
- specialAward.confirmWinner moves from awardMasterProcedure to
  protectedProcedure (juror+chair check inside)
- bulkInviteJurors creates JURY_MEMBER accounts and, when the award has
  a juryGroupId, also adds them to that JuryGroup so they appear on
  the round-page jury panel
- jury award page renders justification, eval-score badges, and a
  chair tools panel with vote tally + finalize-winner CTA
- juryGroup.list includes attached SpecialAwards; the jury-list UI
  shows a trophy pill alongside round pills
- (award-master) route group, awardMasterProcedure, AWARD_MASTER role
  enum value, and AWARD_MASTER_DECISION decisionMode are deleted
- migration demotes any residual AWARD_MASTER users to JURY_MEMBER and
  recreates the UserRole enum without the value

Coup de Coeur on prod: Didier (the sponsor juror added today as
AWARD_MASTER by the buggy invite form) was migrated to JURY_MEMBER and
attached to the existing "Coup de Coeur" JuryGroup; the SpecialAward
itself was linked to that group (juryGroupId was NULL).
