feat: introduce KIM versioning support with new extensions and updates to existing structures

[patrick-werner]

• feat: added ConnectionTypeKimVersionEx extension on Endpoint.connectionType to capture the KIM version (KimVersionVS) and xxl-mail support (boolean)
• feat: added EndpointFADIdEx extension on Endpoint to capture the Fachdienst-ID (FAD) of a KIM endpoint
• feat: added EndpointFADIdEx to alias.fsh as $IdentifierFAD = https://gematik.de/fhir/sid/fachdienst-id
• feat: added ConnectionTypeKimVersionEx as a named extension slice on EndpointDirectory.connectionType
• feat: added Invariant KimConnectionTypeInv enforcing that if ConnectionTypeKimVersionEx is used on connectionType, then connectionType must be #kim from EndpointDirectoryConnectionType
• change: breaking replaced version-specific KIM codes #kim-1.0, #kim-1.5, #kim-2.0 in EndpointDirectoryConnectionType with a single generic #kim "KIM Endpoint" code; the KIM version is now expressed via ConnectionTypeKimVersionEx. This feature was not used yet for KIM, so no migration of existing data is needed.
• change: breaking reduced cardinality of ownerTelematikId on HealthcareServiceDirectory and PractitionerRoleDirectory from 0..* to 0..1
• feat: added OwnerTelematikIdEx (ownerTelematikId 0..1 MS) to LocationDirectory
• change: reorganized alias.fsh with section comments; removed unused identifier aliases ($NamingSystemTelematikID, $IdentifierBSNR, $NamingSystemBSNR, $IdentifierKZVA, $NamingSystemKZVA, $IdentifierIKNR, $NamingSystemIKNR, $IdentifierLANR, $NamingSystemLANR)
• feat: added KimVersionCS CodeSystem with codes #1.0, #1.5, #2.0
• feat: added KimVersionVS ValueSet including all codes from KimVersionCS
• feat: added EndpointDirectoryKIMappTags CodeSystem as placeholder for future KIM appTag codes (#not-present)
• feat: added EndpointDirectoryKIMappTags to EndpointPayloadTypeVS
• feat: added KIMEndpointExample example instance for a KIM 2.0 endpoint with ConnectionTypeKimVersionEx and EndpointFADIdEx
• feat: added active MS to PractitionerDirectory
• fix: set PractitionerDirectory.identifier[TelematikID] to min cardinality 1..
• fix: removed active 0..0 restriction from PractitionerDirectoryStrict
• change: set LocationDirectory.address to 1.. MS (was MS only)

data migration

• EndpointDirectoryConnectionType: replace instances using #kim-1.0, #kim-1.5 or #kim-2.0 with #kim; set the KIM version via the new ConnectionTypeKimVersionEx extension on Endpoint.connectionType using codes from KimVersionCS (kim-1.0, kim-1.5, kim-2.0). As this feature was not used yet for KIM, no migration of existing data is needed.
• HealthcareServiceDirectory and PractitionerRoleDirectory: if multiple ownerTelematikId extensions are present, reduce to at most one

Durchgesehen und keine Probleme entdeckt. Ich warte mit der Übernahme auf Simplifier noch ein wenig, ob sich für den nächsten arvato CR weitere Änderungswünsche ergeben.
