remove camelcase from api responses

[iuwqyir]

TL;DR

Updated JSON field names to follow consistent snake_case convention and added backward compatibility for deprecated fields.

What changed?

• Renamed decodedData to decoded in transaction and log responses
• Changed indexedParams to indexed_params and nonIndexedParams to non_indexed_params
• Added deprecated versions of the params fields to maintain backward compatibility
• Added swagger documentation tags to mark deprecated fields

How to test?

1. Make API requests that fetch decoded logs and transactions
2. Verify new snake_case fields contain the expected data
3. Confirm deprecated camelCase fields still work and contain the same data
4. Check swagger documentation reflects the deprecated status of old fields

Why make this change?

To establish consistent snake_case naming conventions across the API while ensuring existing integrations continue to work through a deprecation period.
