  wxGUI: Skip size event in MapPanelBase.OnSize to let AUI lay out panes (#7941)

wxWidgets 3.3 (wxPython 4.3) changed wxAuiManager to bind its size
handler to the managed window instead of pushing itself as an event
handler. Bound handlers run newest first and stop at the first one
that does not skip the event, so the map panel's own size handler,
bound after the manager was created, swallowed the event. The manager
never laid out its panes and the map window kept its initial size.

Diagnosed with the help of Claude Code.
