Pull request overview

Adds a new Credential Requests API capability to create requests from app/module selections (v2 endpoint), plus an accompanying MCP tool definition, and updates tests/mocks. The PR also includes broad formatting-only changes across several files.

Changes:

• Add credentialRequests.createByModules(...) API method + exported types for the provider/body shapes.
• Add MCP tool credential-requests_create-by-modules with a JSON schema for provider selection (existing Make user vs new user invite).
