UtxoEventQuery

Query for a UTxO event subscription.

Wraps a scalus.cardano.node.UtxoQuery — reusing its source/filter algebra and the inline DSL — and adds an event-type set, so a subscriber can ask for only Created events without a downstream collect.

The pagination fields on the inner query (limit, offset, minRequiredTotalAmount) are snapshot concepts and are ignored for subscriptions; they stay on UtxoQuery because BlockchainReader.findUtxos does honour them.
