Update the Feature flag list view UI to use a complex list instead of a table.

Release notes

Problem to solve

The current UI for browsing a list of feature flags is based on a table layout that makes it difficult to accommodate a large amount of data, especially horizontal data. This leads to an interface that is difficult for users to quickly digest and understand.

Proposal

Move away from the table layout by moving to a complex list where the main data is on the left, metadata is in the middle, and the actions are on the right.

Additional Information

If the delete action has not been added to the detail view, we may need to break this issue into two:

Break the table Move the Toggle

Update as the work is ready.

The ^12345 format for the Feature Flag ID may change. This UI moment should stay plain text but represent the standard for communicating feature flags IDs.
