[miele] Clean up properties and improve reliability and performance (#11423)

* Use appliance cache for getting full UID with protocol prefix instead of relying on property.
* Set bare protocol name as property.
* Fix potential null pointer access warnings.
* Remove unused import.
* Renamed property protocol to protocolAdapter for correctness.
* Add connectionType property.
* Add appliance model property.
* Remove useless properties brandId and companyId always having value MI.
* Rename property dc to deviceClass and set it consistently (not only from auto-discovered things).
* Added constants for remaining handlers with hardcoded device classes.
* Fix SCA: AuthorContributionDescriptionCheck
* Fix SCA: ModifierOrderCheck
* Rename ExtendedDeviceStateUtil to be a bit more generic.
* Extract device class string parsing to utility method.
* Fix SCA: ForbiddenPackageUsageCheck
* Fix redundant null check.
* Fix potential null pointer access warnings.
* Fix unsafe null type conversion (type annotations)
* Share same configuration (UID) for all appliance types.
* Refer to gateway instead of ZigBee network in configuration.
* Remove dependency to seriaNumber property for multicast channel updates.
* Simplified filtering of irrelevant device class.
* Remove devices from remoteUid cache also when disappearing from gateway, although this is a quite rare scenario.
* Add default i18n properties file.
* Add partial Danish translation.
