Refactor and streamline project setup and management scripts

- Removed `run.sh` and `test.sh` scripts to simplify the project structure.
- Added `setup-first-install.sh` to handle initial setup tasks with options to skip specific steps.
- Updated `invario-stack-autostart.service` to use `gitea.sh` for starting the stack on boot.
- Removed `start-stack-on-boot.sh` as its functionality is now integrated into the service.
- Enhanced `admin_system.html` with a new live logs panel, including automatic updates and log source selection.
- Improved CSS styles for the new logs panel for better UI consistency.
- Added JavaScript functionality to fetch and display live logs from the server.
