Refactor Dispatcharr install script for uv and systemd

Switches Python environment setup and package installation to use uv, updates PostgreSQL version to 17, and streamlines database credential creation. Replaces direct systemd ExecStart commands with wrapper scripts for Gunicorn, Celery, Celery Beat, and Daphne, and updates systemd service files for improved reliability. Adds extra proxy headers to Nginx config and improves overall script structure and messaging.
