## Summary
This PR extracts a TileAlertEditor component for future re-use in the Raw-SQL Alert UI. The UI has been updated to make the alert section collapsible and co-locate the "Remove Alert" button within the alert section. The collapsibility will be more important in the Raw SQL case, since the Raw SQL Editor is already pretty vertically tall.

### How to test locally or on Vercel
This must be tested locally, since alerts are not supported in local mode.
