[client] Use the netbird logger for ice and grpc (#3603)

updates the logging implementation to use the netbird logger for both ICE and gRPC components. The key changes include:

- Introducing a gRPC logger configuration in util/log.go that integrates with the netbird logging setup.
- Updating the log hook in formatter/hook/hook.go to ensure a default caller is used when not set.
- Refactoring ICE agent and UDP multiplexers to use a unified logger via the new getLogger() method.
