Improve error logging for Debezium encoding failures

[takaidohigasi]

Bug Report

What happened

When Debezium encoding fails, the current error log lacks context information:

[ERROR] ["write Debezium field value meet error"] [error="..."]

This makes it difficult to debug which table/column caused the issue.

What you expected to happen

Error log should include detailed context information:

• schema/table name
• column name
• value that caused the error
• commitTs (useful for skipping problematic events)
