fix(config): add Reload method to properly re-read config from disk

The /admin/reload endpoint was calling Load() without first calling
ReadInConfig(), meaning the config file wasn't being re-read from disk.
This caused the in-memory config to be out of sync with the file.

- Add Reload() method to ConfigService interface
- Implement Reload() in config service that calls ReadInConfig() then Load()
- Update handleReload to use Reload() instead of Load()
- Regenerate mocks
