feat(device): replace daily wakeHour with multi-time wakeTimes (minutes)

Frame settings now offer two update-frequency modes: "at specific times" or
"every X minutes". Times are stored as an int[] of minutes-since-midnight,
allowing multiple slots per day at minute granularity. Backend computes the
earliest upcoming slot for X-Interval-Ms and uses the most-recent-past slot
as the rotation-due boundary. PWA settings sheet has hour/minute/AM-PM
dropdowns with + Add / trash, a live "next update" preview, and a note
that changes only take effect at the device's next sync.
