feat(service-auto): săpt 3-phase2 — toate ipotezele confirmate + modul funcțional

Backend:
- service_auto module complet: router, service, schemas, 5 teste suites (22/22 passed)
- 5 endpoints: GET /ping, /firme, /tip-deviz, /masini, POST /comenzi
- SP_CREEAZA_COMANDA_PROTOTIP creat în MARIUSM_AUTO (VALID, 5.9ms)
- oracle_pool.py: session_callback backward-compat patch
- ROA_WEB user: grants SP-only confirmate (H3), mariusm_test pool switchat
- pyproject.toml: integration pytest marker înregistrat

Frontend:
- ComandaNoua.vue: date reale din Oracle (firme/tip-deviz/masini), nu hardcodate
- src/modules/service-auto/services/api.js: axios service cu Bearer token
- src/router/index.js: rută /service-auto/comanda-noua

Docs:
- decision-log.md: verdict MERGE, toate 6 ipoteze CONFIRMED
- learnings.md: 7 patterns reutilizabile
- grants-audit.md: arhitectura multi-tenant + proxy auth analysis + V_NOM_FIRME loop
- template-modul-oracle.md: rețetă completă pentru module Oracle noi
- TODO-phase2.md: 7 items concrete
