[Monitoring] Address multiple accessibility issues (#20619)

* Add screen reader only text for monitoring charts

* Add aria label for completed recoveries

* Ensure we have aria label coverage for monitoring chart tooltips

* Ensure table rows are tabbable and include the number of results at the top

* Use EuiScreenReaderOnly

* Updated copy

* Use EUI

* Remove kui usage

* Use an id instead of aria-label

* Show results in the table footer

* Revert "Show results in the table footer"

This reverts commit d622eb7eb4.

* Show total row count within the monitoring table

* PR feedback

* PR feedback

* Ensure all charts show an interval in the tooltip

* Fix padding issue with the cluster status
