Upload an evidence file to a dispute

Streams an evidence file (pdf, png, jpeg, or csv) to tenant-scoped object storage and records the resulting object key on the dispute as a new evidence item. The comment arrives as a query parameter and the file bytes as the request body. The tenant is resolved from the JWT and the dispute from the path — never from the body. Fails closed (503) when object storage is not configured; rejects oversize bodies (413) and unsupported content types (415).
