feat(deploy): enhance database management and configuration

- Updated .env.example to clarify database password usage for OpenWebUI.
- Modified compose-up.sh to ensure databases are created if they do not exist after bringing services up.
- Added ensure-databases.sh script to check and create necessary Postgres databases.
- Adjusted health check for Nextcloud service in docker-compose to point to the correct status endpoint.
- Updated OpenWebUI's DATABASE_URL to use environment variables for Postgres credentials.
