ENG-3252: Remove redundant and flickering tooltip from Action Center view

[nreyes-dev]

Ticket ENG-3252

Description Of Changes

The full URN tooltip on Action Center monitor field rows duplicated the path already shown in each row's visible breadcrumb, and was reported as flickering while hovering/scrolling. This PR removes it, following the precedent of #7962 (ENG-3428) which removed a similarly redundant/buggy tooltip from the Activity tab.

How it looked before

The Cookie_House_BigQuery.prj-bqextract-419116.cms_publisher.users.last_login visibile in the image's tooltip doesn't add any information to the breadcrumb.

Code Changes

• Removed the <Tooltip title={urn}> wrapper around the breadcrumb in MonitorFieldListItem.tsx.
• Removed the now-unused Tooltip import from fidesui in the same file.
• Added a Fixed changelog fragment.

Steps to Confirm

1. Run the admin UI against a Plus backend with discovery monitor data.
2. Navigate to Detection & Discovery → Action center, then open a datastore monitor (e.g., a BigQuery monitor with field-level results).
3. Hover over the breadcrumb paths in the field rows and confirm no URN tooltip appears.
4. Confirm the breadcrumb itself still renders the dataset / schema / table path inline as before.
