fix: resolve TypeScript compilation errors

Fixes:
- VideoPlayer.vue: restore allTags, filteredMarks, marksByTag (removed by mistake)
- PeopleView.vue: fix frameTime scope in playFaceDetailVideo catch block
- Both errors caused white screen on build failure

Root cause:
1. visibleTags duplicate declaration (old + new logic)
2. frameTime undefined in catch block (scope issue)

Solution:
1. Keep allTags/filteredMarks/marksByTag (needed in template)
2. Keep visibleTags (new logic for processor toggles)
3. Move frameTime calculation to correct scope in catch block
