Fix handlers to match decompiled production code

- ButtonHandler: Removed MapText/TextColor/Font (not in production), fixed namespace - LabelHandler: Added CharacterSpacing/LayoutAlignment/FormattedText, ConnectHandler gesture logic - EntryHandler: Added CharacterSpacing/ClearButtonVisibility/VerticalTextAlignment - EditorHandler: Created from decompiled (was missing) - SliderHandler: Fixed namespace, added ConnectHandler init calls - SwitchHandler: Added OffTrackColor logic, fixed namespace - CheckBoxHandler: Added VerticalLayoutAlignment/HorizontalLayoutAlignment - ProgressBarHandler: Added ConnectHandler/DisconnectHandler IsVisible tracking - PickerHandler: Created from decompiled with collection changed tracking - ActivityIndicatorHandler: Removed IsEnabled/BackgroundColor (not in production) - All handlers now use namespace Microsoft.Maui.Platform.Linux.Handlers - All handlers have proper null checks on PlatformView - Updated MERGE_TRACKING.md with accurate status 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
