Consolidate PHP and Nginx Dockerfiles

- Merge separate PHP and Nginx Dockerfiles into a unified structure under `app/docker/Dockerfile`.
- Simplify build stages and streamline multi-service configuration for production, development, and utility containers.
- Remove outdated individual Dockerfiles (`php/Dockerfile` and `web/Dockerfile`).
