Renames all OAuth providers that inherit from OAuthDCRProxy to explicitly include "DCR" in their names, clarifying their Dynamic Client Registration implementation approach. Changes: - GitHubProvider → GitHubDCRProvider - GoogleProvider → GoogleDCRProvider - AzureProvider → AzureDCRProvider - WorkOSProvider → WorkOSDCRProvider - Auth0Provider → Auth0DCRProvider - AWSCognitoProvider → AWSCognitoDCRProvider All old names remain as deprecated aliases with warnings that respect settings.deprecation_warnings. Environment variables updated to include _DCR_ with backwards compatibility via env_prefixes.
