feat(ui): human-confirmed status suggestion banner

When a job workspace opens, loads /status-suggestion and shows a
dismissible banner when a recent inbound email implies a status move
("This email looks like a move to Interview"). Applying it PATCHes the
status; nothing changes without the user's click.

- StatusSuggestion type + load-on-open effect + apply handler
- warning-toned banner shown above tab content on any tab
- EN/NB translations; README endpoint docs
- 2 frontend tests; full suite green (21 suites / 48 tests)
