fix(runtime): update WebhookConfig call-sites for new retry fields

After the rebase onto master, two WebhookConfig { ... } struct literals
added in fe3ec58 (zeroclaw-labs#5799) no longer compile without the three retry
fields introduced in dd93422. Both are test-only call-sites, so `None`
is correct for each.
