Adds a 'Clear Cache' button entity in Home Assistant that clears the HTTP cache and Service Worker CacheStorage, then reloads the webview. This allows remotely recovering from bloated SW caches without physical access to the device. - integration.js: initCacheClear() registers the MQTT button - webview.js: clearCacheView() clears cachestorage + serviceworkers via Electron session API before reloading Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>

Can you confirm that the cache-clear button decreases RAM usage immediately? |

Service Worker CacheStorage can grow to several GB on long-running kiosk displays (observed: 5.9 GB). While the root cause can be fixed on the app side by versioning cache names, having a remote cache-clear button provides a practical recovery mechanism without needing physical access to the device.
