* Add file

* Make types even more fixed

* fix: correct test case for SKU label not provided scenario

The test "should not render SKU label when not provided" was incorrectly using baseContent which includes a SKU label. Fixed by creating contentWithoutSku that explicitly sets skuLabel to undefined to properly test the scenario where no SKU label is provided.

* Fine I'll do it myself

* fix linter

* Refactors

* Adjustments from PR review. Adjustments to video experience (poster/play button) and starting to translate

* Fix i18n

* Accept use case in CWS login, redirect to proper team, with filtered content in preview modal

* Wrap translation strings with defineMessage for i18n extraction

- Add import for defineMessage and MessageDescriptor from react-intl
- Update type definition to use MessageDescriptor for better type safety  
- Wrap all skuLabel, title, and subtitle objects with defineMessage() calls
- This ensures the i18n-extract tool can properly detect translation strings

* Remove unnecessary CSS properties from preview modal content

Remove display: flex, height: 100%, and flex-direction: column from .preview-modal-content selector as they have no effect per code review feedback.

* feat: use getBool selector instead of get for boolean preference check

- Replace getPreference with getBool to avoid explicit === 'true' comparison
- Follows Harrison's review suggestion for cleaner boolean handling
