Simplify fastops: merge docker modules, remove orphaned .py files

- Merge core, compose, caddy, apps → docker.py (fastai-style, succinct)
- Remove orphaned .py files with no notebook sources: proxy, detect,
  compliance, secrets, ship, aws, azure (wrong merge cleanup)
- vps.py: simplify hcloud_auth, add packages/pip_pkgs to deploy()
  for dependency installs on provisioned VPS, use fastcore.listify
- multipass.py: update import (core → docker), unchanged otherwise
- __init__.py: import from docker, vps, cloudflare, multipass only
- _modidx.py: updated to reflect new 4-module structure
