Exports the full Equal Earth map as a ~4K PNG via an off-screen RenderTexture2D, reusing the existing Map2D/Overlays drawing code (already parameterized by an arbitrary target Rectangle) at scale. Extracted the overlay-drawing body of renderMap2D() into a shared, scale-parameterized Viewer::drawMapOverlays() so on-screen and export rendering can never diverge. Fixed a real bug found while testing: the toolbar button called exportMapImage() synchronously from inside drawToolbar()'s active scissor mode (for its scroll panel), clipping the export to a tiny corner. Now deferred via a pending flag and run right after drawToolbar() returns.
