feat(T2): reconciliere anti-duplicat + retry/backoff + recuperare orfane
Inchide bucla de trimitere (plan.md sect. 4 worker, failure registry).
- app/reconcile.py: match_finalizata pe vin+dataPrestatie+odometruFinal (int),
alege id maxim la duplicate (RAR accepta duplicate, confirmat live)
- app/rar_client.get_finalizate: parseaza data.content (descoperit live ca
ruta = GET /prezentari/getAllPrezentariFinalizate; filtrele nu merg pe test)
- app/worker rescris:
- recuperare orfane (rand 'sending' peste lease = worker mort mid-POST)
- pe eroare tranzitorie/timeout: reconciliere INAINTE de re-send (anti-duplicat);
daca recordul exista la RAR -> sent fara re-POST
- retry/backoff exponential; peste worker_max_retries -> error + banner
- re-login la token expirat (JWT 30h)
- schema: coloana next_attempt_at (backoff) + migrare aditiva in init_db
- config: worker_sending_lease_s, worker_retry_base_s/max_s, worker_max_retries
- contract: documentata ruta+forma getAllPrezentariFinalizate (verificat live)
Verify: pytest 54 passed (15 noi T2) + validare live (reconciliere record 68514).
