[TRPD-181][fix] GUI: on window resize, resize all tabs

[pieleric]

With wxPython, only the currently shown tab is resized to the current window size.
So a tab only get the size of the window at the moment it is selected
and shown.

That causes two issues:

• at init, until the tab is shown, its size is very tiny, and most of
  the drawing either doesn't happen or does odd things.
• when the tab is shown, it is resized, which causes a ~0.1s flash that is
  not pretty for the user

=> Resize the all the tabs when the main window is resized. For
efficiency, we do this at most every 0.5s.

In particular, this fixes an issue where on the SPARC the first acquisition
would not be displayed zoomed in. That's because the content fitting
happened with the tab still sized at 0px width.

Pull request overview

This PR updates the GUI tab controller so that when the main window is resized, all tab panels are resized (not only the currently visible one), reducing first-show layout glitches and improving perceived responsiveness when switching tabs.

Changes:

• Bind a main-frame resize handler to propagate sizing to all tab panels.
• Add rate-limited logic (0.5s) to update hidden tabs’ panel sizes to match the shown tab.

📝 Walkthrough

Walkthrough

TabBarController now listens for main-frame resize events. It skips initially tiny dimensions and propagates valid events. A throttled refit resizes non-current tab panels to the current tab’s valid size and lays out panels whose size changed.
