[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.

+## Local Development Setup
+
+These instructions will guide you through setting up the project for local development.
+
+### Prerequisites
+
+- Python 3.11 or later
+- [uv](https://github.com/astral-sh/uv) - A fast Python package installer and resolver.
+- **Docker and Docker Compose** - Required for running the PostgreSQL database.
+- Git
+
+> **Note:** This application requires PostgreSQL, which uses `ArrayField`. Docker is the recommended way to run PostgreSQL locally.
+
+### 1. Install Dependencies
+
+This project uses `uv` to manage dependencies and `poe-the-poet` for task running. First, [install `uv` if you don't have it yet](https://docs.astral.sh/uv/guides/install-python/).
+
+Then, sync the project dependencies. This will create a virtual environment in `.venv` and install all necessary packages, including `poe-the-poet`.
+
+```bash
+uv sync --dev
+```
+
+> **Note on RDkit:** If you have a different version of rdkit installed globally, the dependency installation may fail. If this happens, please uninstall the global version and run `uv sync` again.
+
+### 2. Set Up Environment File
+
+Copy the example environment file for local setup:
+
+```bash
+cp .env.local.example .env
+```
+
+This file contains the necessary environment variables for local development.
+
+### 3. Quick Setup with Poe
+
+The easiest way to set up the development environment is by using the `poe` task runner, which is executed via `uv run`.
+
+```bash
+uv run poe setup
+```
+
+This single command will:
+1. Start the PostgreSQL database using Docker Compose.
+2. Run database migrations.
+3. Bootstrap initial data (anonymous user, default packages, models).
+
+After setup, start the development server:
+
+```bash
+uv run poe dev
+```
+
+The application will be available at `http://localhost:8000`.
+
+#### Other useful Poe commands:
+
+You can list all available commands by running `uv run poe --help`.
+
+```bash
+uv run poe db-up         # Start PostgreSQL only
+uv run poe db-down       # Stop PostgreSQL
+uv run poe migrate       # Run migrations only
+uv run poe bootstrap     # Bootstrap data only
+uv run poe shell         # Open the Django shell
+uv run poe clean         # Remove database volumes (WARNING: destroys all data)
+```
+
+### Troubleshooting
+
+*   **Docker Connection Error:** If you see an error like `open //./pipe/dockerDesktopLinuxEngine: The system cannot find the file specified` (on Windows), it likely means your Docker Desktop application is not running. Please start Docker Desktop and try the command again.
+
+*   **SSH Keys for Git Dependencies:** Some dependencies are installed from private git repositories and require SSH authentication. Ensure your SSH keys are configured correctly for Git.
+    *   For a general guide, see [GitHub's official documentation](https://docs.github.com/en/authentication/connecting-to-github-with-ssh/generating-a-new-ssh-key-and-adding-it-to-the-ssh-agent).
+    *   **Windows Users:** If `uv sync` hangs while fetching git dependencies, you may need to explicitly configure Git to use the Windows OpenSSH client and use the `ssh-agent` to manage your key's passphrase.
+
+        1.  **Point Git to the correct SSH executable:**
+            ```powershell
+            git config --global core.sshCommand "C:/Windows/System32/OpenSSH/ssh.exe"
+            ```
+        2.  **Enable and use the SSH agent:**
+            ```powershell
+            # Run these commands in an administrator PowerShell
+            Get-Service ssh-agent | Set-Service -StartupType Automatic -PassThru | Start-Service
+
+            # Add your key to the agent. It will prompt for the passphrase once.
+            ssh-add
+            ```
