Screen.Recording.2024-03-21.at.17.40.13.mov

🧪 How to test

• Go to the Observability > Alerts page
• Use filter and saved query functionalities, they should work as expected.
• APM > Alerts tab should not show the filters, we can enable them separately if we want to.

Inspired by what @umbopepato implemented for the global alerts page!

When using saved queries, if the query is manually removed by clicking the x on the query, it cannot be loaded again via saved queries until clear all is selected.
