feat(registratura): add legal deadline tracking system (Termene Legale)

Full deadline tracking engine for Romanian construction permitting:
- 16 deadline types across 5 categories (Avize, Completări, Analiză, Autorizare, Publicitate)
- Working days vs calendar days with Romanian public holidays (Orthodox Easter via Meeus)
- Backward deadlines (AC extension: 45 working days BEFORE expiry)
- Chain deadlines (resolving one prompts adding the next)
- Tacit approval auto-detection (overdue + applicable type)
- Tabbed UI: Registru + Termene legale dashboard with stats/filters/table
- Inline deadline cards in entry form with add/resolve/remove
- Clock icon + count badge on registry table for entries with deadlines

Also adds CLAUDE.md with full project context for AI assistant handoff.
