Ensure the message composer textarea scrolls into view during mobile keyboard interactions.
- extract a reusable textarea scroll helper guarded for missing scrollIntoView support
- subscribe to visualViewport resize for all compose modes (not only replies) and clean up listener with stable callback
- trigger textarea scrolling on focus to proactively keep the composer visible when soft keyboards open
- add tests covering visualViewport resize for new compose, existing reply flow, and focus-triggered scroll behavior
