Unify auth and MCP servers into single modular codebase

- Merge auth-server and mcp-server into unified architecture under src/modules/
- Add configurable auth modes: internal (single process) and external (separate processes)
- Update example scripts to support OAuth discovery and both auth modes
- Consolidate OAuth documentation into comprehensive implementation guide
- Add configuration options for development vs production deployments
- Support both Redis-backed and in-memory session storage
