Android tablet remote UI: styling pass, color picker, arrange mode indicator, connection gating

- Button styling standardization with green ring state indicators (Connect, Rescan, Log, Clear Layout, Reset ALL)
- Input field labels with proper DP-based padding and spacing
- Feedback & title widget color picker with 7-color palette and persistence layer
- Font weight selection for text widgets (deferred visual implementation)
- Hide/Show and Reset Size buttons in context menu
- Flashing pink border around entire app when Arrange mode is ON (500ms fade in/out cycle)
- Arrange button disabled until connected to desktop app, with alpha indicator
- WidgetLayoutState now persists color and fontWeight properties
- Arrange mode visual debugging with smooth fade animation instead of harsh strobe
