feat(registratura): AC validity 12/24 months + reminder config in Ghid termene

- Add ACValidityPeriod type (12 | 24) and validityMonths field to ACValidityTracking
- Replace hardcoded 12-month validity with configurable dropdown (12/24 luni)
- Update computed dates, reminder counter, and tooltip to use selected period
- Add "Configurare remindere si alerte" section in Ghid termene with:
  - Threshold table (urgent 5z, depasit 0z, CU alert 30z, AC monthly, prelungire 45z lucr, anuntare 10z cal, transmitere 1z)
  - Pause/resume explanation for clarification requests
- Update AC expiry description to mention configurable 12/24 month validity
