Unify attachment display and enable file uploads on all platforms (#1501)

Attachment pills were drawn by four separate style sets, so files,
images, GitHub items, and reviews rendered at different heights in the
same tray. Move the frame, the two-line label, and the image thumbnail
into shared components so every attachment lines up at one height,
across both the composer and sent messages.

Sent-message images now open the lightbox, and file uploads work on
iOS and Android via expo-document-picker instead of being gated to
desktop.
