chore: add webhook payload examples

[MantisClone]

Problem

Yorvi (aka. Cheetah) needs current webhook payload examples in the main public documentation. The Client ID linking and KYT examples are only available in a separate orchestrator guide, while payment confirmation and Secure Payment Page examples are already on the main Webhooks page.

REQ-455

Proposed Solution

• Add the current client_id.linked payload example to the main Webhooks reference.
• Add the current kyt.screening.completed payload example to the same reference.
• Leave endpoint registration, event routing, and the existing orchestrator guide unchanged.

Considerations

• This PR documents current payloads only. The broader Client ID/orchestrator delivery and identity guidance is in chore: consolidate webhook guidance #130.
• fix: remove unused webhook event variants #129 stacks on this PR.

UAT

1. Open the Mintlify preview.
2. Confirm it includes examples for client_id.linked and payment.confirmed.
3. Confirm the KYT screening payload includes kyt.screening.completed.
4. Confirm the Secure Payment user-event payload remains available.
5. Confirm the existing payment-confirmation and Secure Payment Page examples remain unchanged.
