Fix: Add -admin.grpc flag to worker for explicit gRPC port (#7926) (#7927)

* Fix: Add -admin.grpc flag to worker for explicit gRPC port configuration

* Fix(helm): Add adminGrpcServer to worker configuration

* Refactor: Support host:port.grpcPort address format, revert -admin.grpc flag

* Helm: Conditionally append grpcPort to worker admin address

* weed/admin: fix "send on closed channel" panic in worker gRPC server

Make unregisterWorker connection-aware to prevent closing channels
belonging to newer connections.

* weed/worker: improve gRPC client stability and logging

- Fix goroutine leak in reconnection logic
- Refactor reconnection loop to exit on success and prevent busy-waiting
- Add session identification and enhanced logging to client handlers
- Use constant for internal reset action and remove unused variables

* weed/worker: fix worker state initialization and add lifecycle logs

- Revert workerState to use running boolean correctly
- Prevent handleStart failing by checking running state instead of startTime
- Add more detailed logs for worker startup events
