feat: deterministic email-driven status suggestions

New EmailStatusClassifier scans a message subject/body for outcome
signals (interview invite, offer, rejection) and suggests a canonical
pipeline status. Priority-ordered so a rejection that mentions the prior
interview still classifies as Rejected. Deterministic - no AI - so it is
instant, reproducible, and safe.

- GET /api/jobapplications/{id}/status-suggestion reads the job's latest
  inbound correspondence (incl. Gmail imports) and suggests a forward
  status move, suppressed when already in/past that stage
- always human-confirmed via the existing PATCH .../status
- 7 classifier unit tests + 2 endpoint integration tests; backend green (133)
