feat(import): T6 gate auto_send pe coduri nou-mapate (OV-1)

- load_mapping_meta: {cod_op_service -> {cod_prestatie, auto_send}}
- has_no_auto_send: verifica daca vreun item rezolvat via mapping are auto_send=0
- reresolve_account: auto_send=0 -> ramane needs_mapping (review_manual stat),
  NU trece pe queued; previne FINALIZATA eronat permanent
- reresolve_account primeste batch_id optional (pregatire T7, urmeaza)
- POST /v1/prezentari: auto_send=0 -> needs_mapping + motiv explicit
- 9 teste: load_mapping_meta, has_no_auto_send, reresolve (zero/unu), POST API
