Subject: [PATCH] fix(chain-adapter): add error logging for EVM balance queries

Previously, errors in getNativeBalance and getTokenBalance were silently
swallowed and returned 0 balance. This made debugging impossible.

Changes:
- Log errors to console.error with chain, address, and RPC URL info
- Add debug logging in DEV mode for tracing balance queries
- This will help diagnose why customer assets are not showing
