fix: address 3 new Bugbot review comments

1. Medium Severity: Wrap getOrSpawnTtyd in try/catch
   - Port exhaustion exception now caught and returns 503 error
   - Prevents unhandled promise rejection that hangs client

2. Low Severity: Change "review" level label to "Needs Investigation"
   - "Pending Review" was misleading - this level means CI failed,
     changes requested, or merge conflicts (active problems)
   - "Needs Investigation" better conveys urgency and action needed

3. Low Severity: Add issue label enrichment to API sessions route
   - Import getTracker and enrichSessionIssue
   - Enrich issue labels synchronously before PR enrichment
   - Matches behavior of SSR page and individual session route
