Add devpi PyPI caching proxy role for indri

Set up devpi-server as a transparent PyPI caching proxy on indri,
accessible via Tailscale at pypi.tail8d86e.ts.net.

- Add ansible role with LaunchAgent (KeepAlive service via mise x)
- Add health checks to indri-services-check script
- Configure to listen on port 3141, data stored in ~/devpi

Note: Manual setup required on indri before provisioning:
1. Add devpi packages to ~/.config/mise/config.toml
2. Run mise install && mise x -- devpi-init --serverdir ~/devpi
3. Set up Tailscale service after ansible provisioning
