Fix dark mode text readability in table view and other elements

- Updated table cell colors to use CSS variables instead of hardcoded values
- Fixed location-cell, details-cell, time-cell text colors for dark mode
- Improved contrast with opacity adjustments for secondary text
- Updated status colors (urgent/warning/normal) to work better in dark mode
- Fixed autocomplete, input-help, disclaimer, and table-info text colors
- All text now properly adapts to both light and dark themes
