Add minimap auto-show for zoom button/hotkey interactions

- Emit view:navigate event in animatedZoomView onStart callback
- Minimap now appears when using zoom buttons (in/out/reset/fit)
- Minimap now appears when using zoom hotkeys (Ctrl+/-/0/1)
- Auto-hides after 2 seconds as expected
- Applies to all animated zoom operations consistently
