fix(mobile): review dictated drafts without opening the keyboard

[Dwite]

What Changed

After dictation finishes, expand the mobile composer into its full-height reading area without focusing the editor or opening the keyboard. Tap the text to edit, or tap the conversation to collapse it. Successful sends clear the review state.

Why

A transcript completed from the collapsed composer stayed in one line. Review should make the text readable without immediately opening the keyboard. The review state is scoped to the thread, with matching feed spacing and safe-area padding.

UI Changes

Before	After

Before/after video

Verified on an iOS 26.5 simulator with temporary simulated recorder and transcript responses. Real microphone capture and speech recognition were not tested. All fixtures were removed before committing.

Validation

• 29 focused voice-input tests pass; mobile TypeScript and formatting checks pass.
• Changed-file lint completes with warnings in existing code.
• Device check: 160-point reading area with no keyboard, tap-to-edit with keyboard, and tap-outside collapse to 36 points.

The new-task composer already uses an expanded editor. This change is in the existing-thread mobile UI and applies independently of provider and connection mode.

Checklist

• This PR is small and focused

Changes

Dictation review flow

Layer / File(s)	Summary
Composer review contract and layout apps/mobile/src/features/threads/ThreadComposer.tsx	ThreadComposer accepts dictation review state and a completion callback. Draft updates invoke the callback. The composer remains expanded during review, and the editor minimum height becomes 160.
Screen review lifecycle and sizing apps/mobile/src/features/threads/ThreadDetailScreen.tsx	ThreadDetailScreen tracks review state per thread, selects review chrome, clears state on focus, send, or collapse, and applies the iOS bottom inset only while the composer is focused.

Priority: ⬇️ Low

Estimated code review effort: 3 (Moderate) | ~20 minutes
