Webhook Endpoint Configuration UI

[Kingsman-99]

Description

Developers and integrators who want to receive payment event notifications have no way to configure webhook endpoints through the UI, requiring manual API calls or direct database edits. A webhook configuration page with endpoint registration, secret rotation, and delivery log should be added to the settings section.

Technical Context

src/app/settings/webhooks/page.tsx (new) renders a list of registered webhook endpoints fetched from src/app/api/settings/webhooks/route.ts (new). src/components/settings/WebhookForm.tsx (new) uses react-hook-form with URL validation for the endpoint field and checkboxes for subscribed event types (invoice.created, invoice.funded, invoice.released). A "Rotate secret" action calls POST /api/settings/webhooks/[id]/rotate and displays the new secret in a one-time reveal modal.

Acceptance Criteria

• A webhooks page in settings lists all registered endpoints with URL, event subscriptions, and status
• Adding a new webhook validates the URL format and requires selecting at least one event type
• The newly created webhook secret is shown once in a modal and cannot be retrieved again from the UI
• "Rotate secret" generates a new HMAC secret and displays it in the same one-time reveal modal
• Deleting a webhook requires a confirmation dialog before the DELETE request is sent
• All CI checks (npm test, npm run build, ESLint/TypeScript) pass and the branch has no merge conflicts
