bug: macOS build fails for firebase_editor on Apple Silicon

[x15sr71]

Description

The firebase_editor project currently fails to build on macOS when running on Apple Silicon machines with modern toolchains. This prevents contributors from running or testing the project on macOS.

Errors Encountered

When running flutter run -d macos on macOS 15.6.1 (M4 Pro, ARM64) with Xcode 16.4 and Flutter 3.35.2, the following errors occur:

1. Invalid plugin reference

   Error: Cannot find flutter_local_notifications:linux

2. Clang unsupported option

   clang: error: unsupported option '-G' for target 'arm64-apple-macos10.12'

3. Deployment target too low

   The macOS deployment target 'MACOSX_DEPLOYMENT_TARGET' is set to 10.11/10.12,
   but the Pods project requires at least 10.13

4. CocoaPods warnings & missing configuration

   • Multiple warnings about mismatched deployment target
   • Missing build phases and linking for Firebase dependencies

Expected Behavior

• flutter run -d macos should complete successfully
• App should launch on macOS without dependency errors

---

Environment

• macOS: 15.6.1 (24G90)
• Chip: Apple M4 Pro (ARM64)
• Xcode: 16.4 (Build 16F6)
• Flutter: 3.35.2
• CocoaPods: 1.16.2

---

Proposed Fix

I have prepared a fix that addresses these issues:

• Remove invalid flutter_local_notifications:linux reference
• Update macOS deployment target to 10.15 (minimum supported)
• Add proper CocoaPods integration for Firebase
• Configure Xcode project with required build phases
• Update Swift AppDelegate to use @main annotation
• Regenerate Podfile.lock with compatible versions

Next Steps

I’ll open a Pull Request with these changes for review.
