Fleet UI: Allow select target search for labels and teams

[RachelElysia]

Issue

Cerra #22448

Description

• Allow users to search labels and teams when selecting entities for live query or live policy
• QA:
• Show more and show less toggle button shows if there are more than 600 characters in the labels/team names
• When a team/label is selected within the show more "hidden" section, that section will automatically be open when coming back from running a query
• Search bar will hide the show more/less button if there isn't any more items to show
• Search bar has a button to clear search

Should this devnote say "above" the limit? Is it saying "if any team/labels are selected that would be truncated, default to showing all of the things" ? If so, it is working like that.

Works great! Shared some thoughts on potential optimizations / style considerations
