Bump versions, add port auto-detection, require .env for WP

- Ollama: 0.32.6 → 0.33.0
- Open WebUI: 0.11.0 → 0.11.1
- WordPress: 7.0 → 7.1
- All compose: ports use env vars for auto-detection
- All deploy.sh: find_free_port() — increments port by 1 until free
- WordPress compose: MYSQL vars require .env (no insecure defaults)
- WordPress deploy.sh: auto-generates .env with random passwords
- WordPress deploy.sh: auto-detects ports for WP, Ollama, and WebUI
