Overhaul applicant portal: timeline, evaluations, nav, resources

- Fix programId/competitionId bug in competition timeline
- Add applicantVisibility config to EvaluationConfigSchema (JSONB)
- Add admin UI card for controlling applicant feedback visibility
- Add 6 new tRPC procedures: getNavFlags, getMyCompetitionTimeline,
  getMyEvaluations, getUpcomingDeadlines, getDocumentCompleteness,
  and extend getMyDashboard with hasPassedIntake
- Rewrite competition timeline to show only EVALUATION + Grand Finale,
  synthesize FILTERING rejections, handle manually-created projects
- Dynamic ApplicantNav with conditional Evaluations/Mentoring/Resources
- Dashboard: conditional timeline, jury feedback card, deadlines,
  document completeness, conditional mentor tile
- New /applicant/evaluations page with anonymous jury feedback
- New /applicant/resources pages (clone of jury learning hub)
- Rename /applicant/competitions → /applicant/competition
- Remove broken /applicant/competitions/[windowId] page
- Add permission info banner to team invite dialog
