Phase 6: schedules, blocklists, allowlists (editors + effective state)

- Weekly schedule editor per device: a Monday-Sunday grid of blocking
  windows, including windows that cross midnight.
- Blocklist/allowlist editor per device: app (Android package / Windows
  process) and site (hostname) entries, tagged by the device platform.
- Effective desired state: a manual lock, an active schedule window, or
  neither. While blocked the allowlist is honoured (Spotify stays while
  other apps are blocked). Published retained with reason schedule/manual.
- Boundary-aware republish loop so a window turns on and off on time,
  and manual lock expiry is cleared promptly.
- CONTROL_TIMEZONE (default Australia/Sydney) with embedded tzdata, so
  wall-clock windows are evaluated in the family zone, not the container.
- Every change is written to the append-only audit log (FR-15).
