Append metered connector API types to the connectors page

[abrahams-wix]

Summary

• Append ConnectorApiRequest, ConnectorApiResponse, and ConnectorApiResponsePhase to the connectors module page during SDK reference generation.
• Keep those types grouped under Type Definitions instead of publishing them as separate pages.

Test plan

• Run npm run create-docs --workspace @base44/sdk.
• Confirm docs/content/interfaces/connectors.mdx contains the three types under Type Definitions.
• Confirm the standalone request, response, and phase pages are removed.
