Fix Google Maps Zone Cutoff

I have a live mobile app running on both iOS and Android that relies on the Google Maps API. Everything functions except one critical feature: the zone cut-off. At the moment users can pan endlessly and the service area isn’t being respected, so requests come in from locations we do not serve.

Your job is to dive into the current codebase, track down what is preventing the polygon- or radius-based boundary from activating, and deliver a clean fix that works consistently on both platforms. Once the bug is resolved, I need a short explanation of the change and a new build I can push straight to TestFlight and Google Play internal testing.

Acceptance will be simple: if I open the updated app, attempt to place a pin outside the predefined service zone and the action is blocked with the correct message, the work is complete.
