Pull Request Overview

This PR adds support for dictionary types in query parameters by introducing a new Query type alias and refactoring the form data structure. The change allows query parameters to be specified as either a map (dictionary) or a list of key-value tuples, similar to how form data is handled.

Key Changes:

• Introduced a Query type that reuses the existing Form enum structure
• Renamed Form::Tuple variant to Form::List for better clarity
• Updated the Request struct to use the new Query type instead of a simple vector extractor
