Observer: fix round history, match admin project info, add AI rejection reason

- Round history infers rejection round when ProjectRoundState lacks explicit
  REJECTED state; shows red XCircle + badge, dims unreached rounds
- Project info section now matches admin: description, location, founded,
  submission links, expertise tags, internal notes, created/updated dates
- Fetch FilteringResult for rejected projects; display AI reasoning + confidence
- Remove cross-round comparison from reports, replace with scoring/criteria insights
- Remove unused AI synthesis placeholder
