Fix supplies

[Alann27]

Summary

• Added getQueryClient to enable querying data from the block currently being indexed.
• Updated the supply logic to save denoms that are not yet stored in the database, removing the need for hardcoding.
• Fixed the StakedSuppliersByBlockAndService and StakedAppsByBlockAndService reports.

Issue

Previously, we were using the query client provided by subql via the api field injected globally, but this client only allowed querying data from the latest block, not from the block being indexed. To address this, we now create a custom query client and specify the height of the block being indexed.

Another issue affected the StakedSuppliersByBlockAndService and StakedAppsByBlockAndService reports: they were not including data from the first service, which led to incomplete results.
