Smittix 2cb62d5f34 Standardize all icons to uniform inline SVG format
Replace emojis throughout the codebase with inline SVG icons using
the Icons utility. Remove decorative icons where text labels already
describe the content. Add classification dot CSS for risk indicators.

- Extend Icons utility with comprehensive SVG icon set
- Update navigation, header stats, and action buttons
- Update playback controls and volume icons
- Remove decorative device type and panel header emojis
- Clean up notifications and alert messages
- Add CSS for classification status dots
