Move stylix config up to flake.nix as config wouldn't build without it,
also move wallpapers directory up to top level to match
Only enable git-sync where it's defined, rather than in home/default.nix
Loads of expressions were a single default.nix in a directory, instead
just make a single directory
Hyprland is the only directory of expressions left
Move a few things around to fit this a bit better
Add home/default.nix to defer "import all" from flake.nix
Remove work email from default account set up, add to work laptop
specifically and only
Clean up a few unused expressions
