Keep the keyboard attached during interactive navigation pops by skipping the normal ChatController editing dismissal while the controller is being interactively popped. Cancel interactive keyboard gestures when a horizontal pop begins, so vertical jitter in the back-swipe gesture does not trigger keyboard-dismiss tracking during navigation. Force the delayed keyboard hide layout update after programmatic dismissal to use an immediate transition, avoiding visible movement after returning to the chat list.

Summary
When the keyboard is open in a chat, starting an interactive swipe-back gesture dismisses the keyboard abruptly instead of keeping it visually synchronized with the navigation transition.
This PR keeps the keyboard attached during interactive chat pops and prevents vertical keyboard-dismiss handling from interfering with the horizontal back-swipe gesture.
Changes
ChatControllerediting dismissal while the controller is being interactively popped.Testing
Tested on a physical iPhone device. Verified that with the keyboard open in a chat, an interactive swipe-back keeps the keyboard transition smooth and does not produce the abrupt jump/dismissal described in the bug report.
