feat(anaf-dedup): ANAF partner dedup + address fix + UI enrichment

Prevent partner duplicates via ANAF CUI verification and dual PL/SQL
search. Fix address matching with street-level comparison and diacritics
normalization. Show partner/address comparison in order detail modal.

- New anaf_service.py: batch ANAF API client with chunking, retry, cache
- PL/SQL: dual CUI search (bare/RO+bare/RO space+bare), 3-tier address
  search (street+city+id_loc → city+id_loc → create), strip_diacritics
  at storage for addresses and partner names
- SQLite: anaf_cache table, 12 new order columns for partner/address data
- import_service: cod_fiscal_override param, return partner/address from Oracle
- sync_service: ANAF batch integration, denomination mismatch detection,
  cache pre-population trigger
- Router: enriched order_detail with partner_info + addresses JSON
- UI: collapsible Detalii Partener + Adrese Comparativ sections in modal,
  auto-expand on mismatch, ANAF badges, mobile address cards
- Dashboard: address quality attention indicator
- New scan_duplicate_partners.py script for one-time duplicate audit
