Per-keystroke 'input' saves can be missed on mobile (predictive text or a fast
tap-away fires no final input event), which lost the whole draft when you switched
chats and came back. Added persistCurrentDraft() — snapshots the composer value
into the current chat's draft key the instant you leave it (selectChat before the
swap, and showWelcome/back). Restore on open was already correct. Skipped while
editing.
