* feat(oidc): oauth2 discovery and endpoint rename
This implements the oauth2 authorization server discovery document, adds tests to the discovery documents, implements an efficiency upgrade to these docs, and renames some endpoints to be uniform.
* fix: oidc issuer path and strip path middleware
This ensures the server.path requests append the base_url to the oidc well-known issuer information and adjusts server.path configuration to only strip the configured path instead of the first level entirely regardless of its content.
* fix: only log the token error and general refactoring
* refactor: factorize base_url functions
* refactor(server): include all paths in startup logging
* refactor: factorize
* refactor: GetExternalRootURL -> ExternalRootURL

This is a required endpoint for OIDC and is one we missed in our initial implementation. Also adds some rudamentary documentaiton about the implemented endpoints.
* This gives admins more control over their OIDC installation exposing options that had defaults before. Things like lifespans for authorize codes, access tokens, id tokens, refresh tokens, a option to enable the debug client messages, minimum parameter entropy. It also allows admins to configure the response modes.
* Additionally this records specific values about a users session indicating when they performed a specific authz factor so this is represented in the token accurately.
* Lastly we also implemented a OIDC key manager which calculates the kid for jwk's using the SHA1 digest instead of being static, or more specifically the first 7 chars. As per https://datatracker.ietf.org/doc/html/draft-ietf-jose-json-web-key#section-8.1.1 the kid should not exceed 8 chars. While it's allowed to exceed 8 chars, it must only be done so with a compelling reason, which we do not have.
