Code Review

This pull request introduces comprehensive masking of sensitive data in sink URIs across various modules, including API validation, sink factories, and logging, to prevent credential leakage. It adds utility functions MaskSensitiveDataInURIForError and MaskSensitiveDataInURLError for consistent error handling. The review feedback identifies a missed masking instance in cdc/model/changefeed.go and a minor formatting error in a concatenated string in cdc/sink/validator/validator.go.
