fix(ios): auto-detect available iPhone simulator for builds

Fixed build script to automatically detect and use available simulators:

Simulator Detection:
- Auto-detects first available iPhone simulator if none specified
- Falls back to generic destination if no iPhones found
- Lists available devices in error messages

Build Destination:
- Uses specific device name when available
- Falls back to generic destination for compatibility
- Handles both named devices and generic destinations

Fixes:
- No longer hardcodes 'iPhone 15 Pro' (which may not exist)
- Works with any available iPhone simulator
- Better error messages showing available devices

Usage:
- ./scripts/build-and-deploy.sh              # Auto-detect
- ./scripts/build-and-deploy.sh 'iPhone 17'  # Specify device

Result: Build script now works with any available simulator
