darmanandClaude Sonnet 5 d7a66f3e3b Reorganize services/ into category subfolders
Group service modules by category (media, network, vpn, identity,
dev, desktop) to make the growing services/ dir easier to navigate.
containers.nix stays at the top level since it's a shared backend,
not a single-category service.
