feat: make stats and last rendered frame panels collapsible

The visual footprint of the client is quite big (520x800 px). This PR allows the use to collapse/expand any of the Global stats, Session infos and Last uploaded frame panels to reduce the vertical visual footprint.

Fixed the wrong size detection at client start issue found by Clou.
