Description

If a follower falls sufficiently behind a leader that it can no longer replicate operations, this is reported on the get follow stats API as part of indices[].fatal_exception.

Currently this information doesn't surface in the UI. We need to add this to our follower index (de)serialization, and show it in the follower index detail panel, similar to how we surface auto follow pattern errors.

Research direction
Examine the existing auto follow pattern error display in `x pack/plugins/cross cluster replication/public/app/sections/home/auto follow pattern list/components/detail panel/detail panel.js` (around line 190). Then identify the follower index data serialization code and add the `fatal exception` field. Finally, replicate the display pattern in the follower index detail panel component.
