When there are no pending changes, `+` reuses the active family's untouched
draft instead of creating a new session (unchanged). But when the reused draft
is the one already on screen, currentSessionId doesn't change, so nothing
navigated and the click gave no feedback. Bump a composerFocusRequest nonce in
the reuse branch and have SessionWrapper's focus effect depend on it, so the
composer re-focuses and the user can type right away.
