[v5] Fix Bottom Sheet Closing on Orientation Change When Modal Exceeds Container Bounds

[coffe0wl]

Motivation:

This PR addresses an issue where the bottom sheet unexpectedly closes when the device orientation changes. The bug occurs when, during an orientation change, the modal's content size exceeds the bottom boundary of its container while the animation is in progress.

The root cause is that the closing logic gets triggered when the modal is detected as being out of bounds, even though no user interaction occurred. This fix ensures that the modal only closes if a user-initiated gesture is detected, preventing unintended dismissals caused by layout recalculations during orientation changes.

This issue specifically occurs when using Dynamic Sizing[v5] or the useBottomSheetDynamicSnapPoints[v4] hook.
