test: add comprehensive tests for CopyIcon and MinAppIcon components (#7833)

* test: add comprehensive tests for CopyIcon and MinAppIcon components

- Add tests for CopyIcon covering default rendering, className merging, and prop passing
- Add tests for MinAppIcon covering default props, custom size, sidebar mode, styles, and edge cases
- Include snapshot tests for both components

* fix: update test snapshots after component styling changes

Update snapshots for CopyIcon and MinAppIcon components to match current
styled-components implementation (replaces inline styles with generated classes).

* refactor: simplify icon component tests based on PR review feedback

- CopyIcon: replace multiple redundant tests with single snapshot test
- MinAppIcon: remove duplicate test that overlaps with snapshot test
- Keep essential business logic tests for MinAppIcon (sidebar behavior, null return)
- Update test snapshots accordingly
