Separate Dashboard and HTTP Endpoint authentication

### Description

We currently provide a single choice for endpoint security that gets applied uniformly to HTTP In nodes and Dashboards alike.
When FF Team auth is enabled, we do also allow you to create HTTP Bearer tokens for accessing endpoints directly.

There is a requirement to be able to treat dashboards and http in nodes separately. For example, to have Dashboards protected via FF Team membership, but allow open access to HTTP In nodes (which can apply their own security checks within the NR flow).
