Replace the flat wall of setting groups with three zones that mirror how
notifications actually flow: a pipeline card framing the master switches
as Record events -> Fan out -> Deliver (with paused-stage explanations),
expandable per-channel cards with collapsed status chips (digest hour,
Discord credential state, failing server channels, SSRF warning), and an
Advanced zone for fanout tuning and retention. Discord's setup wall
becomes a collapsible guide; settings stay editable while a channel is
off so admins can configure before enabling. Same setting keys and form
plumbing throughout.
