[Feature] Documentation for development setup

## Summary

This PR improves the local development setup experience by adding Docker Compose and Makefile for streamlined setup.

## Changes

- **Added `docker-compose.yml`**: for one-command PostgreSQL database setup
- **Added `Makefile`**: Convenient shortcuts for common dev tasks (\`make setup\`, \`make dev\`, etc.)
- **Updated `README.md`**: Quick development setup instructions using Make
-
- **Added**: RDkit installation pain point documentation
- **Fixed**: Made Java feature properly dependent

## Why these changes?

The application uses PostgreSQL-specific features (\`ArrayField\`) and requires an anonymous user created by the bootstrap command. This PR makes the setup process trivial for new developers:

```bash
cp .env.local.example .env
make setup  # Starts DB, runs migrations, bootstraps data
make dev    # Starts development server
```

Java fix:
Moved global Java import to inline to avoid everyone having to configure the Java path.

Numerous changes to view and settings.
- Applied ruff-formatting

## Testing

Verified complete setup from scratch works with:
- PostgreSQL running in Docker
- All migrations applied
- Bootstrap data loaded successfully
- Anonymous user created
- The development server starts correctly.
