Update HaCasa

Updating HaCasa is handled by HACS.

1. Open HACS.
2. Open the HaCasa repository page.
3. Choose Update when an update is available.
4. Restart Home Assistant after HACS finishes the update.

If you made local edits inside www/community/HaCasa, back them up before updating. HACS owns that folder and can replace files during an update.
