feat: cleanup unused types from common/index.ts

- Remove 104 unused type exports from packages/client/src/common/index.ts
- Keep only 7 actually used exports (93% reduction)
- Add cleanup script with enhanced import pattern detection
- Support both named imports and namespace imports (* as t)
- Create automatic backups and comprehensive documentation
- Maintain type safety with build verification
- No breaking changes to existing code

Kept exports:
- TShowToast, Option, OptionWithIcon, DropdownValueSetter
- MentionOption, NotificationSeverity, MenuItemProps

Scripts: cleanup-common-types-safe.js, README-CLEANUP.md
