improve token balances mv

[iuwqyir]

TL;DR

Added validation checks for token balance materialized view to ensure data integrity.

What changed?

Added additional WHERE clause conditions in the token balances SQL query to validate that:

• topic_2 and topic_3 are not empty
• ids_length equals amounts_length

How to test?

1. Execute the materialized view creation query
2. Verify that only logs with non-empty topic_2 and topic_3 are processed
3. Confirm that logs where ids_length matches amounts_length are included
4. Check that malformed logs are properly filtered out

Why make this change?

To prevent processing of invalid or malformed log entries that could lead to incorrect token balance calculations. This ensures data consistency and accuracy in the materialized view.
