feat: unify docs portal and MCP servers into one config-driven service

- add config.yml as single source of truth for collected repos/categories
- add collect.py CLI to pull lib/api/wiki site builds and mcp bundles from
  source repos and regenerate nginx.conf + _index/index.html
- port mcp runtime (main.py/core.py/config.py): nginx + health + FastMCP
  servers started from config.yml
- docker: python:3.13-slim + nginx, expose 8000-8006 + 9000 (html portal)
- drone: publish html (6007:9000) and MCP ports 8000-8006
- move mongo-ops docs to wiki/, add auth-server (api) and hexa (lib)
- refresh lib site builds (lib/ prefix) and collect mcp bundles
