chore(spec): regenerate authorable-surface after merging main (#4876)

The merge of origin/main resolved `authorable-surface.json` to this
branch's side, silently dropping the 16 rows #4974 (#4001 批 11) added
for `automation/Webhook` and `integration/WebhookConfig` — main's own
committed baseline had them. Regenerating via `gen:schema` (the gate's
own proof path, never a hand edit) restores both sides: the sibling's
webhook rows and this branch's `ui/DashboardWidget:responsive [RETIRED]`.
