This commit reflects an intentional reorganization of the project.
- Deletes obsolete root-level files.
- Restructures the admin and gallery components.
- Tracks previously untracked application modules.
This commit introduces a `docker-compose.yml` file to simplify the
process of building, running, and managing the application.
- Defines the `bpb-website` service with build context, port mapping,
and environment variables.
- Mounts a volume for `update.json` to ensure data persistence across
container restarts.
- Sets `restart: always` to ensure the service is automatically
restarted if it goes down.
