Add hiring, AI parser+admin, OTP auth, employer dashboard, profit-share pay

- Hiring (استخدام) listings: JobOpening + /Jobs browse/detail + home section
- Heuristic Persian listing-parser + admin queue (/Admin) → publish shift/job
- Phone-OTP cookie auth + visitor-history linking + profile; Admin role gate
- Employer side: self-serve facility registration, dashboard, post/manage shifts & jobs, applicants list with contact
- Compensation models: fixed / hourly / profit-share (درصدی) / negotiable / choice (به انتخاب شما); SharePercent + JalaliDate.PayLabel; parser + filter
