Balance snapshot generation and querying uses a fixed realm

[steven-sheehy]

Problem

The balance snapshot generation and querying uses a hardcoded account 0.0.2 for the base account. This needs to be adapted or non-zero realms.

Solution

• Change the balance snapshot generation process to use the shard and realm properties
• Change anywhere that queries the account_balance with 0.0.2 to add shard and realm to the query
