Configure API server endpoints for iOS/Android development builds

Updated scripts/common.sh to set appropriate API server endpoints based on build mode:
- Development: localhost:3000 for Endorser API, production for Image/Partner APIs
- Test: test-api.endorser.ch for Endorser API, production for Image/Partner APIs
- Production: All production endpoints

This ensures mobile builds use correct API endpoints for each environment
while keeping Image and Partner APIs on production servers for dev/test.
