feat(oracle): support per-article id_pol in PACK_IMPORT_COMENZI + deploy docs

- PACK_IMPORT_COMENZI: reads optional "id_pol" per article from JSON, uses it
  via NVL(v_id_pol_articol, p_id_pol) — enables separate price policy for
  transport/discount articles vs regular order articles
- README.md: add Windows deploy section (deploy.ps1, update.ps1, .env example)
- CLAUDE.md: add reference to Windows deploy docs

+## Deploy Windows
+
+### Instalare initiala
+
+```powershell
+# Ruleaza ca Administrator
+.\deploy.ps1
+```
+
+Scriptul `deploy.ps1` face automat: git clone, venv, dependinte, detectare Oracle, `start.bat`, serviciu NSSM, configurare IIS reverse proxy.
+
+### Update
+
+```powershell
+# Ca Administrator
+.\update.ps1
+```
+
+### Configurare `.env` pe Windows
+
+```ini
+# api/.env — exemplu Windows
+ORACLE_USER=VENDING
+ORACLE_PASSWORD=****
+ORACLE_DSN=ROA
+TNS_ADMIN=C:\roa\instantclient_11_2_0_2
+INSTANTCLIENTPATH=C:\app\Server\product\18.0.0\dbhomeXE\bin
+```
+
+**Important:**
+- `TNS_ADMIN` = folderul care contine `tnsnames.ora` (NU fisierul in sine)
+- `ORACLE_DSN` = alias-ul exact din `tnsnames.ora`
+- `INSTANTCLIENTPATH` = calea catre Oracle bin (thick mode)
+
+### Serviciu Windows (NSSM)
+
+```powershell
+nssm restart GoMagVending    # restart
+nssm status GoMagVending     # status
+nssm stop GoMagVending       # stop
+```
+
+Loguri serviciu: `logs/service_stdout.log`, `logs/service_stderr.log`
+Loguri aplicatie: `logs/sync_comenzi_*.log`
+
+### Depanare SSH
+
+```bash
+# Conectare SSH (PowerShell remote, cheie publica)
+ssh -p 22122 gomag@79.119.86.134
+
+# Verificare .env
+cmd /c type C:\gomag-vending\api\.env
+
+# Test conexiune Oracle
+C:\gomag-vending\venv\Scripts\python.exe -c "import oracledb, os; os.environ['TNS_ADMIN']='C:/roa/instantclient_11_2_0_2'; conn=oracledb.connect(user='VENDING', password='ROMFASTSOFT', dsn='ROA'); print('Connected!'); conn.close()"
+
+# Verificare tnsnames.ora
+cmd /c type C:\roa\instantclient_11_2_0_2\tnsnames.ora
+
+# Verificare procese Python
+Get-Process *python* | Select-Object Id,ProcessName,Path
+
+# Verificare loguri recente
+Get-ChildItem C:\gomag-vending\logs\*.log | Sort-Object LastWriteTime -Descending | Select-Object -First 3
+```
+
+**Nota SSH:** Userul `gomag` nu are drepturi de admin — `nssm restart` si `net stop/start` necesita PowerShell Administrator direct pe server.
+
+### Probleme frecvente
+
+| Eroare | Cauza | Solutie |
+|--------|-------|---------|
+| `ORA-12154: TNS:could not resolve` | `TNS_ADMIN` gresit sau `tnsnames.ora` nu contine alias-ul DSN | Verifica `TNS_ADMIN` in `.env` + alias in `tnsnames.ora` |
+| `ORA-04088: LOGON_AUDIT_TRIGGER` + `Nu aveti licenta pentru PYTHON` | Trigger ROA blocheaza executabile nelicențiate | Adauga `python.exe` (calea completa) in ROASUPORT |
+| `503 Service Unavailable` pe `/api/articles/search` | Oracle pool nu s-a initializat | Verifica logul `sync_comenzi_*.log` pentru eroarea exacta |
