`paginate` does not cap `limit` — a caller can force an enormous response

[Jaydbrown]

contracts/factory/src/query.rs paginate and DripFactory::streams_by_sender / streams_by_recipient explicitly do not bound limit ("callers should use a reasonable value"). A caller passing limit = u32::MAX makes the contract build a Vec<u64> up to the length of the sender's entire history in a single view call. Clamp limit to a hard maximum (e.g. 100) inside paginate.
