Code quality improvements to UniFi integration (#45794)
* Do less inside try statements

* Replace controller id with config entry id since it doesn't serve a purpose anymore

* Improve how controller connection state is communicated in the client and device tracker
Remove the need to disable arguments-differ lint

* Remove broad exception handling from config flow
I'm not sure there ever was a reason for this more than to catch all exceptions

* Replace site string with constant for SSDP title_placeholders

* Unload platforms in the defacto way

* Noone reads the method descriptions

* Improve file descriptions
