Add webhook name field to improve webhook identification (#37025) (#37040)

Add an optional Name field to webhooks so users can give them
human-readable labels instead of relying only on URLs. The webhook
overview page now displays names when available, or falls back to the
URL for unnamed webhooks.

Fixes #37025
