Pull Request Overview

This PR introduces support for specifying HTTP methods for endpoints (including GET for one-time verification) and adds a dedicated Okta verification handler.

• Extend the endpoint schema to include an optional method field with allowed HTTP verbs.
• Update the API router to dynamically mount routes using the configured HTTP method (defaulting to POST).
• Implement OktaSetupHandler with acceptance tests and update docs/config examples for the new method option.

• Consider adding unit tests for Api.create to verify that endpoints are correctly mounted with custom HTTP methods and that the default POST fallback works as expected.
