feat(service-auto): săpt 1 POC Oracle + module scaffold

- poc/hello_oracle.py: sync connect 33ms, DEV_TIP_DEVIZ enum verified live
- poc/hello_oracle_async.py: async 22ms, gate Correction 9 → sync-facade
- backend/modules/service_auto/{routers,services,schemas,models}: scaffold
- docs/service-auto/week1-notes.md: DX latency + gate decision
- docs/service-auto/TODO-phase2.md: phase 2+ backlog (empty header)

+# Săpt 1 Notes — Oracle POC
+
+**Date**: 2026-04-11
+
+## Conectivitate
+
+- Server: `central` (10.0.20.121:1521/ROA, CONTAFIN_ORACLE) — PORT OPEN, direct (no tunnel needed)
+- Sync connect: **33ms** | Queries: 0.6-3.3ms ✅
+- Async connect_async: **22ms** | Queries: 0.2-0.3ms ✅
+
+## Gate Correction 9 — Decizie
+
+**Decizie: sync-facade pattern** (consistent cu `oracle_pool.py` existent)
+
+Motivare: `oracle_pool.py` folosește deja `oracledb.create_pool()` (sync) + `pool.acquire()` (sync) + `with cursor` (sync) în `async def`. Serviciile service_auto vor urma același pattern pentru consistență arhitecturală. `connect_async` funcționează dar nu aduce beneficii față de sync-facade la latențele măsurate.
+
+## Schema Access
+
+- `MARIUSM_AUTO.DEV_ORDL` — acces OK
+- `MARIUSM_AUTO.DEV_TIP_DEVIZ` — enum confirmat (7 tipuri, inch_validare corect)
+
+## Next Steps (Săpt 3)
+
+- Audit grants `ROA_WEB` pe `MARIUSM_AUTO.*`
+- Creare SP `SP_CREEAZA_COMANDA_PROTOTIP` în MARIUSM_AUTO (template în tabele-service-auto.md §12.2)
+- Auth path: adaugă `MARIUSM_AUTO` company în `.env` + test login JWT end-to-end
