feat: admin can fill in evaluations on behalf of jurors

When a juror cannot connect during an evaluation round, an admin
can now submit evaluations for them.

Router — new admin procedures:
- adminStart / adminAutosave: create and save drafts for any juror.
- adminSubmitOnBehalf: submit bypassing ROUND_ACTIVE and voting-window
  checks. COI block and feedback/criterion validation still enforced.
  Audit log records both admin and juror IDs plus bypassedWindow flag.
- getJurorAssignmentsForRound: list a juror's assignments + eval state.

UI — two new admin pages under /admin/rounds/[roundId]/jurors/[userId]/:
- evaluate: list of pending + completed assignments, COI flagged.
- evaluate/[projectId]: evaluation form reusing the juror's scoring UI,
  with an "acting on behalf" banner and confirmation dialog before
  submit. Back button returns to the assignments list.

Entry point: FilePen icon on each juror row in JuryProgressTable.

Refactor: extracted the scoring form JSX into shared
EvaluationFormFields component so the juror page and the admin proxy
page render identical inputs.
