Regenerate stale Java client protobuf code

The checked-in generated Java sources under clients/java/src/main/generated/
were out of sync with both the .proto contracts and the configured
protobuf 4.33.1 toolchain: they were missing the alarm command kinds
(MX_COMMAND_KIND_SUBSCRIBE_ALARMS..ACKNOWLEDGE_ALARM_BY_NAME, 25-29), the
alarm/galaxy message additions, and the protobuf 4.x generated-code layout.
Regenerated via `gradle generateProto`; `gradle test` passes against the
refreshed sources. No hand edits — pure protoc/protoc-gen-grpc-java output.
