Improve logging for lock reset silent skip and failure paths

- Raise usercode fetch failure from debug to warning level
- Add warning log when lock_config_entry is None
- Add warning log when entity missing from registry
- Add debug log for unsupported platform (expected skip)
- Add warning log when lock instance missing in clear/adopt paths
