Change Package Name

Follow the common Flutter app guide for the full package-name change procedure:

Package Name Setup ↗

eBroker-specific notes

• Do this BEFORE Firebase setup. Firebase config is bound to your package name; changing it after Firebase is configured forces a re-download of google-services.json and the Firebase platform reconfiguration.
• After running the rename command, also update androidPackageName in lib/settings.dart so app code references the new ID.
