feat: avize deadline restructure with interruption mechanism + comisie toggle

- Add "Necesita analiza in comisie" toggle for avize category (mirrors CJ toggle)
  - When OFF: auto-creates 5-day working limit for completari requests
  - When ON: no limit (institution can request completions anytime)
- Add interruption mechanism: resolve aviz as "intrerupt" when institution
  requests completions → auto-creates new 15-day deadline from completions date
- New resolution type "intrerupt" with yellow badge + chain support
- Restructure avize catalog entries:
  - aviz-ac-15 (L50) and aviz-urbanism-30 (L350) now have chain to
    aviz-emitere-dupa-completari for interruption flow
  - aviz-mediu: updated hints about procedure closure prerequisite
  - aviz-cultura-comisie: 2-phase with auto-track depunere la comisie (30 days)
  - aeronautica, ISU, transport-eu: all get interruption chain
- 3 new auto-track entries: aviz-completari-limit (5zl), aviz-emitere-dupa-completari
  (15zc), aviz-cultura-depunere-comisie (30zc)
- New document type: "Convocare sedinta"
- Info boxes in dialog explaining auto-track behavior + interruption mechanism
