fix: replace text-white with theme-aware color tokens (#7908)

## Summary
- Replace hardcoded `text-white` class with theme-aware alternatives to
fix invisible text on light themes
- Update Load3D control backgrounds to use semantic tokens
- Update dropdown menus to use `bg-interface-menu-surface`
- Update overlay backgrounds to use `bg-backdrop` with opacity

## Changes
| Component | Old | New |
|-----------|-----|-----|
| Text on primary bg | `text-white` | `text-base-foreground` |
| Dropdown menus | `bg-black/50` | `bg-interface-menu-surface` |
| Control panels | `bg-smoke-700/30` | `bg-backdrop/30` |
| Loading overlays | `bg-black bg-opacity-50` | `bg-backdrop/50` |
| Selected states | `bg-smoke-600` | `bg-button-active-surface` |

## Files Modified (14)
- `src/components/TopMenuSection.vue`
- `src/components/input/MultiSelect.vue`
- `src/components/load3d/*.vue` (12 files)
- `src/renderer/extensions/vueNodes/VideoPreview.vue`

## Test plan
- [ ] Verify text visibility in light theme
- [ ] Verify text visibility in dark theme
- [ ] Test Load3D viewer controls functionality
- [ ] Test MultiSelect dropdown checkbox visibility
