[FEATURE] - Sonarr/Radarr/Prowlarr - Prevent reinstallation on every script run

[insuusvenerati]

Is your feature request related to a problem? Please describe.
When restarting an *arr container, the script spends a lot of time setting up even if a lot of dependencies already exist and are set up.

Describe the solution you'd like
Check for existing setup of configuration / deps and skip what can be skipped when the script is run

Describe alternatives you've considered

• Manually run the script when needed
• Check for existing setup in a separate script
