webMethods API Gateway SaaS - Add OAuth2 support with DPoP (RFC 9449) for API authentication and authorization

Currently, the API Gateway supports OAuth2 with traditional proof-of-possession mechanisms (Bearer tokens).

To enhance the security of exposed APIs and comply with recent standards, we plan to add support for Demonstration of Proof of Possession (DPoP) as defined in RFC 9449.

DPoP allows you to link an OAuth2 access token to a cryptographic key held by the client, thereby reducing the risks associated with token theft or reuse (replay attacks, token leakage).
