chore(deploy): Docker production config, nginx gzip/cache, deploy docs

- docker-compose.yml: restart always, env_file, named volume, start_period
- frontend/nginx.conf: gzip compression, cache headers for assets, no-cache for SW
- Makefile: add prod-down and prod-logs targets
- docs/DEPLOY.md: Dokploy + Cloudflare Tunnel deploy instructions

+# ROA AUTO - Deploy Guide
+
+## Prerequisites
+
+- Docker & Docker Compose installed
+- Domain configured (e.g., roaauto.romfast.ro)
+- Cloudflare Tunnel configured (or reverse proxy)
+
+## Production Deploy on Dokploy
+
+### 1. Clone and configure
+
+```bash
+git clone <repo-url> roaauto
+cd roaauto
+cp .env.example .env
+```
+
+Edit `.env` with production values:
+
+```
+SECRET_KEY=<generate-a-strong-secret>
+DATABASE_URL=sqlite+aiosqlite:///./data/roaauto.db
+SMSAPI_TOKEN=<your-smsapi-token>
+CORS_ORIGINS=https://roaauto.romfast.ro
+```
+
+Generate a secret key:
+
+```bash
+python3 -c "import secrets; print(secrets.token_urlsafe(64))"
+```
+
+### 2. Build and start
+
+```bash
+make prod-build
+make prod-up
+```
+
+Verify:
+
+```bash
+curl http://localhost/api/health
+# {"status":"ok"}
+```
+
+### 3. Run initial migration
+
+```bash
+docker compose exec backend alembic upgrade head
+```
+
+### 4. Seed catalog data (first deploy only)
+
+```bash
+docker compose exec backend python -m app.db.seed
+```
+
+## Cloudflare Tunnel Setup
+
+1. Install `cloudflared` on the Proxmox host
+2. Create a tunnel: `cloudflared tunnel create roaauto`
+3. Configure the tunnel to route `roaauto.romfast.ro` to `http://localhost:80`
+4. Run as a service: `cloudflared service install`
+
+The tunnel provides HTTPS termination - nginx listens on port 80 internally.
+
+## Dokploy Configuration
+
+If using Dokploy instead of manual Docker:
+
+1. Create a new project in Dokploy
+2. Set source to your Git repository
+3. Set compose file to `docker-compose.yml`
+4. Add environment variables from `.env.example`
+5. Set the domain to `roaauto.romfast.ro`
+6. Deploy
+
+## Maintenance
+
+### Logs
+
+```bash
+make prod-logs
+```
+
+### Database backup
+
+```bash
+make backup
+```
+
+### Update deployment
+
+```bash
+git pull
+make prod-build
+make prod-up
+```
+
+### Rollback
+
+```bash
+git checkout <previous-commit>
+make prod-build
+make prod-up
+```
+
+## Architecture
+
+```
+Internet → Cloudflare Tunnel → nginx (:80)
+                                 ├── / → SPA (static files)
+                                 └── /api → backend (:8000)
+
+backend: Python 3.12 + FastAPI + SQLite (file-based)
+frontend: Vue 3 SPA served by nginx
+data: ./backend/data/ (bind mount, persisted)
+```
