ENG-3428: remove buggy and redundant action center activity tab tooltip

[nreyes-dev]

Ticket ENG-3428

Description Of Changes

Removes the hover tooltip on error messages in the Action Center Activity tab. The tooltip duplicated the content already shown by the inline "more" expand button (in a less readable way), was visually overwhelming for long SQL errors, and exhibited a flickering bug from hover-detection races.

Code Changes

• Removed tooltip: true from the Paragraph ellipsis config in InProgressMonitorTaskItem.tsx. The expandable: true / symbol: "more" behavior is preserved.

Steps to Confirm

1. Spin up a Plus environment with at least one monitor task in error status.
2. Navigate to Data inventory > Action center, open a monitor, and select the Activity tab.
3. Hover over the error message text on a row with an "Error" badge.
4. Confirm no tooltip appears on hover, and that clicking the inline more button still expands the full error message.
