feat: add output hash of inputs to scanning stream (#7334)

Description
---
adds spent output hashes to the stream by utxo block for the utxpo
scanner
fixes limites

<!-- This is an auto-generated comment: release notes by coderabbit.ai
-->
## Summary by CodeRabbit

* **New Features**
* Added an `inputs` field to UTXO sync responses, allowing clients to
receive input data alongside outputs when syncing by block.

* **Improvements**
* Enhanced UTXO sync logic to ensure all inputs are included and chunked
appropriately, even if their count exceeds outputs.
* Applied a global request body size limit of 4 MiB to the HTTP server
for improved consistency.

* **Tests**
* Updated test mocks to include the new `inputs` field in UTXO sync
responses.
