Fix GrampsWeb: patch service worker to respect subpath (STI-90)

The GrampsWeb service worker was serving index.html for ALL navigation
requests (including Django app routes), hijacking the entire domain.
Patched sw.js at startup to:
- Use subpath-prefixed index.html in createHandlerBoundToURL
- Update denylist regex to match subpath API routes
