🐛(frontend) preserve left panel width on window resize

[Ovgodd]

Purpose

Fix a bug where the left panel unexpectedly expanded or shrank when the window was resized. The expected behavior is that the left panel width should remain constant unless manually adjusted by the user.

issue 1573

rezisable.mp4

Proposal

• Remove global recalculation of min/max panel size on window resize
• Track panel width in pixels (savedWidthPxRef) and convert it to % only when needed
• Force the panel to maintain its width percentage equivalent after resize

I can see some flickering:

It is because react-resizable-panels is percent based I think, so we have to compute the size every time to keep it fixed.

Could you give a try to this lib instead ?

Let's merge it.
