Add delete-self; fix offline cache & connectivity

Introduce a Supabase Edge Function (supabase/functions/delete-self) and call it from AuthRepository to perform a signup rollback (delete auth user) when profile creation fails; log rollback errors and still sign out. Fix offline repositories to use proper Map<String, dynamic> casts when reading cached JSON and to persist JSON maps (via toJson) when caching models. Simplify connectivity providers by returning the original status stream and using the provider's asData value for isOnline/isOffline to avoid extra stream wrapping. Add a 1-hour grace parameter (configurable) to getOverdueDoses in health_improvements. Also add .claude/settings.local.json to .gitignore.
