chore(ui): Playground settings / show more / trials area

[m-rgba]

Description

• Updated trials view to be re-sizable (added re-sizable component which can be used for alternative drawers).
• Tweaked trial header buttons / added sticky header.
• Updated Show More buttons to be smaller and fixed old overlay issues to have them sit on top (updated the backgrounds to make them a little less visually weighted as well).
• Fixed issue with MessagePanel and tool calls having show more + max-height.

Lgtm, except a small fix necessary

I think the show more is resizing in the drawer incorrectly.
The show more is only showing the last like 20 pixels regardless of the height of the content.

Will fix - interesting, yeah it only looks like that's in the trials, in the regular chat views it seems to be the right height
