feat(changelog): add support for native recovery (#3624)

Adds the ability to complete the recovery flow properly on API flows. This PR also streamlines the behavior for SPA flows to not return 422 errors anymore. To enable this new behavior, set the features.use_continue_with_transitions flag in the config to `true`.
