fix(ios): stabilize keyboard toolbar, image picker, and scrolling (#15182)

## Summary
- keep the editor active when iOS keyboard toolbar interactions move
focus into range-sync excluded widgets
- use the native iOS image picker/source sheet and sync native
presentation with the app theme
- pin `ListViewKit` to `1.1.6` so the iOS workspace resolves with Xcode
16.3
- restore vertical scrolling in the iOS `WKWebView` by removing the
global `contentOffset` reset while preserving zoom prevention

## Test plan
- [x] `yarn vitest --run --config \"vitest.config.ts\"
--browser.enabled=false \"src/__tests__/inline/active.unit.spec.ts\"`
- [x] `LANG=en_US.UTF-8 LC_ALL=en_US.UTF-8 xcodebuild
-resolvePackageDependencies -workspace
\"packages/frontend/apps/ios/App/App.xcworkspace\" -scheme \"App\"`
- [x] `xcodebuild -workspace \"App.xcworkspace\" -scheme \"App\"
-destination \"generic/platform=iOS Simulator\" build
CODE_SIGNING_ALLOWED=NO ONLY_ACTIVE_ARCH=YES ARCHS=arm64`
- [x] Xcode build validation for the updated PR branch
