[EXPERIMENTAL] Create file upload session

POST 
/v1/files

Creates a new file upload session by generating a presigned PUT URL for direct S3 upload with server-side size enforcement.

Clients must PUT the raw file bytes to the returned uploadUrl with the correct Content-Type and Content-Length headers.

Both headers are signed into the URL via SigV4, so S3 rejects any PUT where either header is missing or differs from the declared values.
