Support touchpad horizontal scroll for browser tab back/forward navigation

Summary
The Codex app browser tab should support back/forward navigation from horizontal mouse-wheel or touchpad scroll gestures, such as a two-finger left/right swipe on a trackpad.
Expected behavior
When focus is in a browser tab with navigation history:
- two-finger swipe/drag left navigates back
- two-finger swipe/drag right navigates forward
- equivalent horizontal mouse-wheel events behave the same way
This matches long-standing behavior in major browsers and makes the embedded browser feel native.
Current behavior
The browser tab does not appear to handle these horizontal scroll gestures for history navigation.
Notes
This should only trigger when the embedded browser view has navigation history and the gesture is not being consumed by horizontally scrollable page content.
