[DEPRECATED] Add a signer to document

[DEPRECATED — will stop working in API v2] This endpoint is kept for backwards compatibility. Use POST /api/v1/documents/:id/parties instead — “party” is the correct term for a document participant.

Add a signer/participant to a document. The signer must reference an existing contact.

Signer Roles:

• SIGNER - Must sign the document
• ORGANIZER - Document organizer (no signature required)
• REVIEWER - Reviews document (no signature required)
• ACCEPTOR - Accepts terms (for acceptance documents)

Per-Signer Settings:

• deliveryMethod - How to notify: EMAIL (default), SMS, or NONE (use signing URL directly)
• requiredSignature - Signature type: DRAWING, BANKID, or CLICK_TO_SIGN
• twoStepVerification - 2FA: NONE (default) or SMS_BEFORE_SIGNING

Signing Order: For SEQUENTIAL signing, specify the order (1, 2, 3…). For PARALLEL signing, order is ignored.

Response: Returns the created signer. Use GET /documents/:id/signers/:signerId to retrieve the signing URL.

POST /api/v1/documents/{id}/signers
