Summary

This PR strengthens validation for lite.bind.topic in LiteTopic consumer groups by:

1. Replacing != null checks with StringUtils.isNotBlank() in LiteMetadataUtil — catches empty-string values that previously passed through.
2. Introducing TopicNameAttribute (extending StringAttribute) to validate topic names at the attribute level via TopicValidator.validateTopic().
3. Adding comprehensive tests for empty/blank lite.bind.topic in both single and batch delete scenarios, plus attribute-level validation.

The defense-in-depth approach (attribute-level validation + runtime isNotBlank checks) is solid. Tests are thorough and cover edge cases well. LGTM.
