Adding aria2 profile templates and associated startup and installation scripts

- Added aria2 profile template with basic options, RPC options, download options, and more.
- Added prepare-aria2-config.sh script for preparing and generating aria2 configuration.
- A new start-aria2.sh script has been added to start the aria2 service and check port availability.
- A new aria2-install.sh script has been added to install aria2 and its dependencies, and to download the AriaNg Web UI.
- All scripts include logging for debugging and monitoring service status.
