fix(examples-chat): unblock canonical demo prod deploy — raise bundle budget + wire Maps key (#776)

The App-mode cockpit (@angular/google-maps + @angular/cdk + map/itinerary)
pushed the production initial bundle ~80kB over the 1.5MB budget; only the
production config enforces budgets, so dev/e2e passed while the 'Canonical
demo → Vercel' job failed at build (frontend never deployed). Raise the
initial budget to 1.75MB (warn 1.6MB), matching the feature's weight.

Also pass GOOGLE_MAPS_API_KEY + GOOGLE_MAPS_MAP_ID to the canonical demo
assemble step (mirroring the ag-ui deploy) so inject-env bakes a keyed
bundle and the App-mode toggle is enabled in prod.
