fix: invalidate Vite module graph on template/style HMR updates

When a template or style file changes, the custom fs.watch callback
clears the internal resourceCache and sends an angular:component-update
WebSocket event. However, it does not invalidate the corresponding
module in Vite's module graph. This causes Vite's transform cache to
serve stale compiled output on full page reloads.

Add a moduleGraph.invalidateModule() call after the WS event is sent
so that Vite re-transforms the component module on the next request.
