feat: observer team tab, admin-controlled applicant feedback visibility

- Add Team tab to observer project detail (configurable via admin settings)
- Move applicant jury feedback visibility from per-round config to admin settings
- Add per-round-type controls: evaluation, live final, deliberation
- Support anonymous LiveVote and DeliberationVote display for applicants
- Add fine-grained toggles: scores, criteria, written feedback, hide from rejected
- Backwards compatible: falls back to old per-round config if admin settings not set
- New admin settings section under Analytics tab with all visibility controls
- Seed new SystemSettings keys for observer/applicant visibility
