feat: remove the custom podman-darwin module

This change removes our custom podman-darwin module that manually managed
Podman machines on macOS. Instead, we now rely on home-manager's native
podman module which includes proper launchd integration for machine
management.

Waits for: nix-community/home-manager#8102
