Animation window can be zoomed out way further than the maximum values allowed

Steps to reproduce:

1. Create a new Unity project using the Universal 3D template
2. Create a new Cube GameObject (GameObject > 3D Object > Cube)
3. Select the newly added Cube GameObject in the Hierarchy window
4. Open the Animation window (Window > Animation > Animation)
5. Create a new Animation
6. Zoom out the Animation window until it stops zooming out
7. Observe the Animation window

Actual results: Animation window can be zoomed out way further than the maximum values allowed, to the point that no keyframes can even be added

Expected results: Animation window has limited zoom to prevent issues

Reproducible with versions: 6000.0.69f1, 6000.3.10f1, 6000.4.0b11, 6000.5.0a8

Tested on (OS): MacOS Silicon Tahoe 26.2

Notes:

• in 6.0, 6.3, and 6.4 the window visually looks different, not even showing the time labels
