* The model+validation referenced tracked_clients and templates columns
but they were never in the unifi_webhook_configs migration. Any save
attempt that included those keys 500'd with "Unknown column".
Added an additive migration (idempotent) that adds both as nullable
json columns.
* New POST /settings/webhooks/test-url endpoint takes a url+secret in
the body and fires the standard test payload. Lets operators validate
their endpoint before saving the row — useful when first wiring up
Google Chat, Slack, etc.
v1.5.4.
