Add jumpcloud IdP (#1124)

added intergration with JumpCloud User API. Use the steps in setup.md for configuration.

Additional changes:

- Enhance compatibility for providers that lack audience support in the Authorization Code Flow and the Authorization - - Code Flow with Proof Key for Code Exchange (PKCE) using NETBIRD_DASH_AUTH_USE_AUDIENCE=falseenv
- Verify tokens by utilizing the client ID when audience support is absent in providers
