Thomas Kosiewski 33bbf18a4b feat: add OAuth2 protected resource metadata endpoint for RFC 9728 (#18643)
# Add OAuth2 Protected Resource Metadata Endpoint

This PR implements the OAuth2 Protected Resource Metadata endpoint according to RFC 9728. The endpoint is available at `/.well-known/oauth-protected-resource` and provides information about Coder as an OAuth2 protected resource.

Key changes:
- Added a new endpoint at `/.well-known/oauth-protected-resource` that returns metadata about Coder as an OAuth2 protected resource
- Created a new `OAuth2ProtectedResourceMetadata` struct in the SDK
- Added tests to verify the endpoint functionality
- Updated API documentation to include the new endpoint

The implementation currently returns basic metadata including the resource identifier and authorization server URL. The `scopes_supported` field is empty until a scope system based on RBAC permissions is implemented. The `bearer_methods_supported` field is omitted as Coder uses custom authentication methods rather than standard RFC 6750 bearer tokens.

A TODO has been added to implement RFC 6750 bearer token support in the future.
