feat(config): add detailed logging for home config changes

- Introduced `logHomeConfigChanges` to compare old and new configs, logging detected differences.
- Leveraged `diff.BuildConfigChangeDetails` for structured change detection.
- Adjusted logging behavior to enable debug-level logs dynamically when required.
