fix(dart): improve ParseAggregate pipeline encoding and remove debug print

- Send each pipeline stage as individual query parameter with JSON-encoded
  value instead of bundling into a single 'pipeline' string, improving
  compatibility with Parse Server's getPipeline() format
- Remove debug print() statement that leaked pipeline URL to console
- Use handleResponse for consistent response handling with other
  ParseObject subclasses

+### Bug Fixes
+
+* Fix `ParseAggregate.execute()` pipeline encoding: send each stage as an individual query parameter with JSON-encoded value instead of bundling into a single `pipeline` string, improving compatibility with Parse Server's `getPipeline()` format
+* Remove debug `print()` statement in `ParseAggregate.execute()` that leaked the full pipeline URL to console
+* Use `handleResponse` in `ParseAggregate.execute()` for consistent response handling with other `ParseObject` subclasses
