[Fleet] fixing dropping select all

[juliaElastic]

Summary

Fixes #133523

Added logic so that query selection (select all) is not dropped on Agent list when data changes.

See detailed reasoning here:
#133523 (comment)

Didn't modify manual scenario, I think it's not right to keep all 20 agents selected when the underlying data changes, as it might result in taking action on agents that were not intended.

To verify:

• enroll a few agents with horde (more than 20 to have multiple pages)
• select all agents in list
• wait until refresh happens in the background
• expect that the select all (query) state is not lost, and actions can still be taken on all agents
• when unselecting one agent manually, the state goes back to manual selection (e.g. 19 selected instead of 20)

After manual unselect (12 agents selected as some of the dropped automatically from view on refresh)

Checklist

• Unit or functional tests were updated or added to match the most common scenarios
