Update config_flow.py to work better with translations

Removed device_count and scanner_count strings. The variables from these strings have been split into separate keys: device_counter_active, device_counter_devices, scanner_counter_active, scanner_counter_scanners. These keys only contain the numerical values ​​and are applied as such in the translation file.

I also tried to move the status messages to the translation file, but I haven't succeeded yet. The preparations for this are already in the .json translation files.
