Strip «آماده به کار» from role names + reject domestic-helper ads

Re-check of live applicants found two gaps:
- «کمک بهیار آماده به کار» — the availability phrase glued onto the role. StripRoleModifiers
  now removes «آماده به کار / آماده همکاری / جویای کار / جهت همکاری» phrases before
  token-stripping, so the role collapses to «کمک بهیار».
- «خانم امورسبک منزل» — light-housework domestic helpers (not کادر درمان). Validator
  now discards ads with «امور منزل / نظافت منزل / خدمتکار / مستخدم …» markers.

Both take effect for existing data on the next applicant reprocess.
