test: fix server tests for provider model passthrough behavior

- Update model-resolver.test.ts to expect unknown models to pass through
  unchanged (supports ClaudeCompatibleProvider models like GLM-4.7)
- Remove warning expectations for unknown models (valid for providers)
- Add missing getCredentials and getGlobalSettings mocks to
  ideation-service.test.ts for settingsService
