FN-5706: hide chat input overflow until max-height

Prevent the chat composer from showing a right-edge scrollbar line before it reaches the autosize cap.

- set chat textarea default overflow to hidden in ChatView CSS
- add resolveChatInputOverflowY to switch overflow to auto only past the 640px cap
- apply overflow mode during composer autosize updates
- extend chat input autosize tests and docs to cover overflow behavior
