Subject: [PATCH] refactor(schedule): dedup formatSendAt into shared
 formatFriendlyDateTime
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

ScheduleMessageModal had a local formatSendAt(Date) byte-equivalent to the
tested formatFriendlyDateTime (utils/datetimeInput). Reuse the shared, unit-
tested helper instead of a second copy — identical output. (Also prettier-clean.)
