Prompt de l'API de création de note de dossier Copier le prompt dans le presse-papiers \

\`Post a note to a case through the Management API.

Endpoint:
POST https://verification.didit.me/v3/organization/{organization_id}/application/{application_id}/cases/{case_uuid}/notes/

Authentication:
Use the x-api-key header with my Didit API key.

Request body:
\{
"comment": "Called the customer, awaiting a reply.",  // required
"mentioned_emails": ["teammate@company.com"],           // optional
"is_internal": false,                                    // optional, default false
"attachments": [{"s3_key": "case-notes//-file.pdf"}],  // optional - upload first via notes/presign/
"tags": ["follow-up"]                                     // optional
}

Behavior:
\- Each attachment's s3_key must be under this case's own case-notes/{case_uuid}/ prefix (returned by the upload endpoint) - otherwise 400.
\- Logs a NOTE_ADDED event and creates mention notifications for mentioned_emails.

Example call:
curl -X POST "https://verification.didit.me/v3/organization/{organization_id}/application/{application_id}/cases/{case_uuid}/notes/" \
-H "x-api-key: YOUR_API_KEY" -H "Content-Type: application/json" \
-d '{"comment": "Called the customer, awaiting a reply.", "tags": ["follow-up"]}'

Response 201: CaseNote.

Failure modes:
\- 400 - an attachment does not belong to this case.
\- 401/403 - auth/permission errors.
