Enhancement: Saving latest block for next shielded sync query

[huvny-de]

Issue:

• In version 0.32.0 Namada SDK, there is a feature to apply for passing 2 attributes start_query_height and last_query_height. It only helps to fetch and scan in specific range of block to optimize shielded sync time.
• For latest code namada-interface doesn't using that. So when shielded sync still need fetching still have to call the API to fetch redundant blocks
