fix(dev): Resolve Dev Debug Environment Issues and Streamline Local Setup

This commit comprehensively addresses issues with the local development and debugging environment, ensuring a smoother and more reliable developer experience.

Key changes include:

- **VSCode Debugger:** Corrected launch configuration (`.vscode/launch.json`) to properly run the Django development server with debugging enabled. It now correctly sets `DEBUG=True`, uses `0.0.0.0:8000`, and specifies the correct working directory.
- **Docker Compose:** Exposed the PostgreSQL port (`5432:5432`) in `docker-compose.yml` to allow direct connections from the host, facilitating local development and debugging without needing to run the full application stack.
- **Environment Variables:**
    - Updated `.gitignore` to ignore all `.env.*` files, allowing for environment-specific configurations.
    - Modified `src/pkmntrade_club/django_project/settings.py` to use `localhost` for `DJANGO_DATABASE_URL` and `REDIS_URL` by default, aligning with the exposed Docker services for easier local development. Default `DISABLE_SIGNUPS` and `DISABLE_CACHE` are now `True` for a more typical local dev setup.
- **Management Commands & Scripts:**
    - Adjusted `manage.py` to correctly append the project's root directory to `sys.path`, resolving potential import issues when running management commands.
    - Significantly improved `scripts/reset-db_make-migrations_seed-data.sh`:
        - Removed reliance on sourcing `.env` directly.
        - Ensured the database service (`db`) is started independently before migrations.
        - Added explicit steps for running `prebuild.sh`, migrations, and `collectstatic`.
        - Switched to using `uv run manage.py loaddata` for seeding, which is more consistent with the project's tooling.
- **Django Settings:** Added `SESSION_ENGINE = "django.contrib.sessions.backends.signed_cookies"` and `SESSION_COOKIE_HTTPONLY = True` for improved session management and security.

These changes collectively fix the previously problematic development setup, enabling straightforward debugging and a more efficient workflow for local development.
