Tobias O ddf1fd3515 Frontpage update (#179)
This PR introduces an overhaul for the front page and login features while keeping the rest of the application intact.

## Major Changes

- TailwindCSS + DaisyUI Integration: Add  modern CSS framework for component-based utility styling
- Build System: Added pnpm for CSS building; can be extended for updated frontend builds in the future
- Navbar + Footer: Redesigned and includable; old version retained for unstyled elements
- Optimized Assets: Added minified and CSS-stylable logos

## New Features

- Static Pages: Added comprehensive mockups of static pages (legal, privacy policy, terms of use, contact, etc.). **Note:** These have to be fixed before a public release, as their content is largely unreviewed and incorrect. Probably best to do in a separate PR that only contains updates to these.
- Discourse API: Implement minimal features based on RestAPI for controllable results.

## Current bugs
- [x] The static pages include the default navbar and footer on the login page. This will likely not work, as users need to access it before logging in; no good workaround so far (problem with Django templating system).
- [ ] The front page predict link is currently non-functional; the redesigned page is almost ready but better done in a separate PR as it also touches Django code.
- [x] Visual bug with the news cards. Still intend to fix for this PR

## 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) - Python package manager
- **Docker and Docker Compose** - Required for running PostgreSQL database
- Git
- Make
> **Note:** This application requires PostgreSQL (uses `ArrayField`). Docker is the easiest 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 installation: if you have rdkit installed on your system globally with a different version of python, the installation will try to link against that and subsequent calls fail. Only option remove global rdkit and rerun sync.
---
The frontend requires `pnpm` to correctly display in development.
[Install it here](https://pnpm.io/installation).
### 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
```
This will start the css-watcher as well as the django-development server,
The application will be available at `http://localhost:8000`.
**Note:** The development server automatically starts a CSS watcher (`pnpm run dev`) alongside the Django server to rebuild CSS files when changes are detected. This ensures your styles are always up-to-date during development.
#### 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 build # Build frontend assets and collect static files
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
```
