Feat: Add Custom Agent Filtering

[humberto-garza]

Justification

For large AzDO pools, it is hard to find agents that need special attention like offline or disabled ones.

Implementation

• Inject a custom regex search bar to the Agent Pool page
• Add a count to the search bar
• Refresh the filter every 10 seconds because the table updates automatically
• Add a button to refresh on demand

Testing

After
