[ci skip] Pass skill secrets to moltbot container and fix Python env

- Add skill_secrets variable to moltbot module with HA tokens and
  Uptime Kuma password as container env vars
- Install Python packages (requests, caldav, icalendar, uptime-kuma-api)
  in init container with PYTHONPATH for main container access
- Update all skills to use python3 directly instead of ~/.venvs/claude
  venv path that doesn't exist in the container
- Remove hardcoded Uptime Kuma password from skill, use env var
