feat: Add desktop collapsed strip widgets

- Add new desktopStripWidgets settings in state.js with toggles for weather, clock, date, location, stats, and attributes
- Add strip widget container in template.html with animated clock face
- Add CSS styles for strip widgets with wider collapsed panel (5rem), vertical layout, and theme support
- Implement updateStripWidgets() in desktop.js to populate widgets from tracker data
- Wire up settings handlers in index.js for all strip widget toggles
- Call updateStripWidgets() on data updates in sillytavern.js integration
- Trigger widget update when panel is collapsed in layout.js

The strip widgets display compact stats/info in the collapsed panel strip on desktop, similar to mobile FAB widgets, eliminating the need to expand the panel to view basic data.
