Improved compatibility logic

The Person patch is now dynamic and adapts automatically to the detected HA core version.

It’s no longer possible to enter a duplicate SSID when editing an existing entry.

The logic for adding and editing SSID/zone entries has been refactored and separated, making the process clearer and more intuitive.

The confusing empty screen shown at the end of the edit process has been removed — the flow now ends cleanly after updating an existing SSID or zone.

Note:
Currently, a warning is shown if an SSID is duplicated (i.e. appears multiple times between the home and extra zones).
In a future version, duplicate SSIDs may be automatically removed, keeping only one instance at random.
