`GET /lead_sources/{lead_source_id}`

Returns one lead source with its contact counts. The path id is the source's system_id — the value contacts carry in their lead_source field — which is separate from the record's internal id. Built-in sources use short slugs like advertisement; ones you create get an ObjectId-style id.
