Add gender requirement (آقا/خانم/فرقی نمی‌کند) + employee (کارجو) panel

- Gender enum + GenderRequirement on Shift/JobOpening + Gender on UserPreferences (migration)
- Employer PostShift/PostJob + admin Review have a gender select; parser detects آقا/خانم/مرد/زن
- Gender badge on cards + detail; gender filter on Shifts/Jobs; gender in preferences
- Recommendations exclude listings whose gender requirement conflicts with the person's gender
- Two panels: new /Me employee (کارجو) panel (recommendations + saved + applied + prefs) alongside /Employer; nav routes by role; /Account/Profile → /Me
