test(cli): cover minimax-oauth resolution, refresh, menu wiring

Add and extend tests for the minimax-oauth provider across three test
modules.

New file: tests/test_minimax_oauth.py (15 tests)
  - test_pkce_pair_produces_valid_s256: verifies PKCE verifier/challenge
    pair produces a valid S256 hash and correct lengths
  - test_request_user_code_happy_path: mocks httpx, verifies correct
    POST parameters and response parsing
  - test_request_user_code_state_mismatch_raises: verifies CSRF guard
  - test_request_user_code_non_200_raises: verifies HTTP error handling
  - test_poll_token_pending_then_success: verifies polling loop retries
    on 'pending' and returns on 'success'
  - test_poll_token_error_raises: verifies 'error' status raises AuthError
  - test_poll_token_timeout_raises: verifies deadline expiry raises
  - test_refresh_skip_when_not_expired: verifies no HTTP call when token
    is fresh
  - test_refresh_updates_access_token: verifies new access/refresh tokens
    stored on successful refresh
  - test_refresh_reuse_triggers_relogin_required: verifies
    relogin_required=True on invalid_grant/refresh_token_reused
  - test_resolve_credentials_requires_login: verifies AuthError when no
    stored state
  - test_provider_registry_contains_minimax_oauth: PROVIDER_REGISTRY key
  - test_minimax_oauth_alias_resolves: portal/global/underscore aliases
  - test_get_minimax_oauth_auth_status_not_logged_in
  - test_get_minimax_oauth_auth_status_logged_in

Extended: tests/hermes_cli/test_runtime_provider_resolution.py
  - test_minimax_oauth_runtime_returns_anthropic_messages_mode
  - test_minimax_oauth_runtime_uses_inference_base_url

Extended: tests/hermes_cli/test_api_key_providers.py
  - TestMinimaxOAuthProvider class (8 tests) covering registry keys,
    auth_type, endpoints, client_id, aliases, CANONICAL_PROVIDERS
    listing, _PROVIDER_MODELS entries, and aux model
