feat(browser): unify site credentials with browser profiles (BR-2)

- Inject the site account Cookie (manual + auto-login session, session wins)
  into the camofox profile before the first tab opens; password accounts
  without a session run refresh-login first; API Key sites are skipped.
- Cookie expired after injection -> credential.status=expired; cookie
  accounts go to waiting/login_required ("log in once, applies site-wide").
- Write back site-domain cookies from the browser on handover, session close,
  every 10 min of activity, and from refresh-login when the stored cookie is
  invalid (verified before saving). user_info.cookieOrigin records
  source=browser; source shown as manual/login/browser in the origin view.
- New camofox plugin umt-cookies (GET/POST /umt/sessions/:userId/cookies
  under the access key); profile dir 0700/files 0600 in the desktop image.
- Single entry: sources-identity/service/credentials.ts.
- Real check: HHClub cookie injected into a fresh profile -> home page
  logged in (logout link present), 5 cookies read back.

Requires rebuilding umt-browser-desktop (docker compose build camofox &&
docker compose up -d camofox) to take effect.
