API Route Definitions & Logic

Summary of API Design

✅ Handles SMS messages and extracts gas levels. ✅ Links SMS to correct sensor and client. ✅ Manages gas readings and updates sensor statuses. ✅ Ensures client location updates propagate. ✅ Handles all logic previously managed in Supabase triggers.

This new structure centralizes the business logic within Next.js, making it easier to debug, test, and maintain while optimizing database interactions. 🚀
