fix(file-based): populate failure_type, internal_message, and exception on CSV encoding error

[devin-ai-integration]

Summary

The UnicodeError handler in csv_parser.py:read_data() raised AirbyteTracedException without failure_type, internal_message, or exception parameters. This caused:

1. Sentry titles the event AirbyteTracedException: None (because internal_message was None)
2. The error is classified as system_error instead of config_error
3. The original UnicodeError stack trace is lost

- except UnicodeError:
+ except UnicodeError as e:
      raise AirbyteTracedException(
-         message=f"... Expected encoding: {config_format.encoding}",
+         message=f"File contains bytes that cannot be decoded with the configured {config_format.encoding} encoding.",
+         internal_message=str(e),
+         failure_type=FailureType.config_error,
+         exception=e,
      )

This follows the same pattern already used elsewhere in the file (lines 178, 186, 212).

Breaking Change Evaluation

Not a breaking change. This is a bug fix that improves error classification and messaging — no schema, spec, stream, or state changes.

Test Coverage

Updated CsvReaderTest.test_read_data_with_encoding_error to verify all new fields: failure_type == FailureType.config_error, internal_message matches the original error string, and _exception preserves the original UnicodeError instance.
