Refactor widgets into separate focused files

Split the two large widget files (~2000 lines combined) into 10 focused files:
- WidgetBundle.swift: Main @main bundle registration
- WidgetModels.swift: Shared data models (WatchTimelineView, SimpleEntry, etc.)
- WidgetProviders.swift: Timeline providers and TimeLineCreator
- WidgetSharedViews.swift: Shared voting views
- FeelsTimelineWidget.swift: Timeline widget (small/medium/large)
- FeelsVoteWidget.swift: Vote widget with stats views
- FeelsIconWidget.swift: Custom icon widget
- FeelsGraphicWidget.swift: Graphic mood widget
- FeelsMoodControlWidget.swift: Control Center widget
- FeelsLiveActivity.swift: Live Activity with proper previews

Preserves real-time update architecture (VoteMoodIntent, WidgetCenter,
WidgetDataProvider patterns). Adds proper Live Activity preview support
with sample content states.
