feat(takserver): bridge Casevac / Emergency / Task + GeoChat receipts

Bump the protobufs submodule to the takv2_geometry commit that adds
CasevacReport, EmergencyAlert, TaskRequest, and GeoChat receipt
fields. Rebuild meshtastic-tak-0.1.0.jar from the updated
TAKPacket-SDK kotlin artifact and extend TakV2Compressor.kt with the
corresponding wireToSdkData / sdkDataToWire branches so the JVM
takserver round-trip preserves every structured field the SDK parser
now extracts.

- .gitmodules: pin core/proto/src/main/proto to takv2_geometry
- core/proto/src/main/proto: fast-forward to the new protobufs tip
- core/takserver/libs/meshtastic-tak-0.1.0.jar: rebuilt artifact
  with the typed CasevacReport / EmergencyAlert / TaskRequest
  payload variants and the extended GeoChat receipt fields
- core/takserver/src/jvmAndroidMain/.../TakV2Compressor.kt:
  * extend wireToSdkData with casevac / emergency / task / chat
    receipt branches, mapping enum .value ints through the SDK
    TakPacketV2Data sealed-class payloads
  * extend sdkDataToWire with the same three variants plus the
    chat receipt_for_uid / receipt_type fields
  * import WireCasevacReport / WireEmergencyAlert / WireTaskRequest
    from the regenerated Wire proto classes
