Refactor ChoiceButtonDialog.vue: streamline template, improve typing

- Extracted all long/repeated CSS class strings in template to computed properties for maintainability
- Added/updated file-level and method-level documentation with comprehensive JSDoc comments
- Replaced $notify type from 'any' to 'unknown' for improved type safety
- Confirmed notification usage is already modern and follows project standards
- No databaseUtil or SQL abstraction required (pure UI component)
- Lint validation successful (no errors, only unrelated warnings remain)
- Migration tracking documents updated with timing and performance metrics

Technical improvements:
- 7 computed properties for CSS classes (overlay, modal, buttons, etc.)
- Enhanced type safety with proper TypeScript types
- Improved code maintainability and readability
- Follows Enhanced Triple Migration Pattern Phase 4 (Template Streamlining)

Migration completed in 7 minutes (13% faster than 8-12 min estimate)
