The notification channel form has a <input hidden name=enabled value=0>
plus a <input checkbox name=enabled value=1> so unchecking the box
still submits 'enabled=0' (otherwise the field would just be absent).
But Go's url.Values.Get returns the FIRST value, so even when the
checkbox is ticked the handler read '0' and persisted enabled=false.
Scan r.PostForm["enabled"] for any '1' instead. Caught during the
sweep — all three test channels saved with enabled=0 even though
the toggle visually rendered ON.
Flagged in review of cd38b40: the Alerts tab badge should show the
open count from any page, not just /alerts. baseView now takes the
request and queries store.ListAlerts(Status: "open") to fill
view.OpenAlerts on every page render. All call sites updated.
