Registers the MCP Adapter as a default mcp_server connector so MCP setup is discoverable from the Connectors screen, reusing the existing install/activate flow. The connector uses authentication => none, so no credential is stored in connector settings.

Also exposes applicationPasswords availability (isSupported, isAvailable, isAvailableForUser, canCreate, username, profileUrl) in the Connectors script module data, so the UI can create an Application Password on request and explain why it's unavailable when it can't.
