fix(workflow): let an unresolvable webhook URL fail loudly

Reverts the guard added earlier in this PR. A blank row titled "Webhook URL"
is a worse outcome than a crash: it explains nothing, and the value is one a
user copies into a third-party provider, so any substitute — a guessed page
origin, an empty string — is a URL that provider accepts and then never
delivers to.

The read can no longer come back empty from the hydration race this PR fixes,
so reaching it at all means the deployment has no application base URL, which
breaks webhook registration and callbacks regardless. The error boundary now
reports what it caught, so the throw names its own cause instead of surfacing
as an unexplained fallback.
