The channel form has three inputs all named 'name' (one per kind
section: webhook / ntfy / smtp), but only the visible kind's input
is filled in. PostForm.Get returns the first regardless of
emptiness, so editing an ntfy or smtp channel always read '' from
the (hidden, unfilled) webhook section's name input and rejected
with 'name required'.
Add firstNonEmpty helper that scans the slice for the first
non-blank value. Same flavour of bug as the enabled checkbox fix
in 24eecc1 — both fall out of having multiple inputs share a name
across the per-kind sub-forms.
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 35dee98: 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.
