Felipe Coury eaff9a5f14 Hide Back to bottom when the current transcript tail is visible (#46902)
## Why

Pausing transcript following can leave the current final row visible, making the “Back to bottom” control unnecessary after copying text, closing find, or enlarging the viewport.

## What changed

Base control visibility on whether the current transcript tail is visible, and hide it for an empty viewport. Keep the control available when a paused view shows an older live revision with new activity.

## Testing

Add regression coverage for empty viewports, copying at the bottom, closing find at the bottom, and resizing a paused view. Extend live-revision assertions and update the composer-gap snapshot to keep the gap blank in the paused detailed view at the tail.
