Portal: per-system daily/weekly schedule editor

System picker lists the account's License Keys labelled by System Name
(fallback: key). Schedule type selector (Daily|Weekly) with a confirmation
before switching a populated schedule (daily->weekly prefills all seven
days; otherwise clears). Weekly shows a per-day editor. Blocks use
TimeInput, allow adjacent/midnight-crossing ranges (labelled 'ends next
day'), block empty blocks client-side, default dynamic audio on, and show
title/category/group only. Adds gap helper text and an informational
kiosk-timezone note (browser fallback; no external/paid dependency).
