remove query rewrites

[Theodus]

After release 2.1.1, client query rewrites are only required for inserting the probe for block data. Ideally we would remove the error-prone rewrite code in favor of independent queries to indexers for that block data. These queries can be far less frequent than client queries typically are for each subgraph chain.

This was attempted in release 24.2.0. However, it requires graphprotocol/indexer-rs#494 to avoid regressions.
