Phil Skentelbery 052d3ad3e1 feat(auth): implement response_type=id authentication flow
Implements both IndieAuth flows per W3C specification:
- Authentication flow (response_type=id): Code redeemed at authorization endpoint, returns only user identity
- Authorization flow (response_type=code): Code redeemed at token endpoint, returns access token

Changes:
- Authorization endpoint GET: Accept response_type=id (default) and code
- Authorization endpoint POST: Handle code verification for authentication flow
- Token endpoint: Validate response_type=code for authorization flow
- Store response_type in authorization code metadata
- Update metadata endpoint: response_types_supported=[code, id], code_challenge_methods_supported=[S256]

The default behavior now correctly defaults to response_type=id when omitted, per IndieAuth spec section 5.2.
