Pull Request Overview

This PR adds support for JSON-encoded POST bodies in the LDAP authentication strategy, complementing the existing form-encoded support. Rails applications automatically parse JSON request bodies into action_dispatch.request.request_parameters, which the strategy now reads via a new request_data helper method.

• Introduced a request_data method that checks for Rails-parsed JSON parameters before falling back to standard form parameters
• Updated all parameter accesses throughout the strategy to use request_data instead of directly accessing request.params
• Added comprehensive test coverage for JSON authentication flows
