Create a presigned upload URL

POST 
/api/v1/files/presigned-url

Creates a short-lived, single-use presigned upload URL — the local-storage equivalent of an S3 presigned URL. The client then uploads the file content directly to the returned upload_url via POST /api/v1/files/upload/{token}, bypassing MCP payload size limits. When the server is configured with SOAT_BASE_URL, upload_url is a fully-qualified absolute URL so MCP agents and other clients can POST to it without knowing the server base URL in advance.
