Fixes#10410
Adds the permission model to the curated communities model.
Also fixes the assetsModel and collectiblesModel used by the community portal, because it was using the basic Chat Store created in AppMain, but that store doesn't have the assets model.
- `StatusCommunityCard` updated with a new hearder component.
- `CommunitiesGridView` updated to use `CommunityPermissionsRow` component inside card.
- Added needed models.
- Updated storybook.
Pending backend integration: Part of task #10410
Additionally:
- communities grid made scrollable
