Thread: the reply box appears on Reply, full width, with its tools on a row beneath.

A thread opened to read came with an empty field under its first post.
The box now appears under the note whose Reply was tapped (or while a
draft is pending), folds away once the reply is sent or Cancel is tapped,
and takes Amethyst's shape: the field across the full width, attach and
preview on a row beneath it with Cancel and Reply at the right.

Tests: thread-reply's helper follows the new shape and expects the box to
fold after sending; compose-preview and feed-list tap Reply before
expecting a box (the thread card carries .thread-card as the marker).
