The shared_oauth_client_credentials fixture was using Dynamic Client
Registration which doesn't support Nextcloud's allowed_scopes parameter.
This caused tokens to lack proper scope configuration, resulting in empty
tool lists when the server validated scopes.
Changes:
1. Updated shared_oauth_client_credentials to use occ oidc:create with
allowed_scopes="openid profile email nc:read nc:write"
2. Created opaque token client (not JWT) for port 8001 compatibility
3. Enhanced _create_oauth_client_with_scopes to support both JWT and
opaque token types via token_type parameter
This ensures:
- Regular OAuth tests (port 8001) get opaque tokens with proper scopes
- JWT OAuth tests (port 8002) get JWT tokens with embedded scopes
- Both token types have allowed_scopes configured on the OAuth client
Fixes test_mcp_oauth_server_connection which was getting empty tool list
