Description

We need to remove the outdated agents' statistic from the Endpoints Summary page. As a result, the state management for the total number of outdated agents needs to be moved to the table component.

Tasks

• Remove the outdated agents' statistic from the Endpoints Summary page.
• Update the table component to handle the state management for the total number of outdated agents.
• Ensure the table component correctly reflects the total number of outdated agents after the change.
• Fix Agent Welcome layout for 850px width.
• Change Endpoint Summary statistics title:
  • TOP 5 AGENTS BY OS -> TOP 5 OS
  • TOP 5 AGENTS BY GROUP -> TOP 5 GROUP

Additional Notes:

• Verify that the removal of the statistic does not affect other parts of the Endpoints Summary page.
• Test the table component thoroughly to ensure the state is managed correctly.
