refactor: rename JackeryHome component directory and update references

- Renamed the `custom_components/JackeryHome/` directory to `custom_components/jackery_home/` for consistency.
- Updated all references in documentation and scripts to reflect the new directory name.
- Removed obsolete files related to the previous directory structure.
