"""Import DBF -> SQLite (T5 — SCHELET, neimplementat inca).

Plan.md sect. 7: dry-run + raport intai (randuri valide, mapari orfane, coduri
necunoscute in nomenclator), apoi scrie in SQLite. Surse:
  - mapare_prestatii.DBF  -> operations_mapping
  - prestatii_rar.DBF     -> nomenclator_rar
(rar_log.DBF NU se migreaza.)

Utilizare (cand e implementat):
    python -m tools.import_dbf --dry-run
    python -m tools.import_dbf --commit

Necesita: pip install dbfread
