Add plasma-manager back, disable stylix theming for KDE in favour of
plasma-manager options.
Reorganise some config - move GTK settings up to desktop.nix since
they're relevant to anything, move xdg portal config into sway only
since plasma sets up it's own.
Move xarchiver to sway only, using ark on plasma.
Add protonmail-bridge-gui for plasma, set to autostart
Remove fonts and scheme from base system, update uses of to point to
stylix instead.
Remove some left over files from the earlier rearrange.
Disable waybar stylix target - TODO write a custom moustache at some
point to re-enable with my custom style
Fix login shell to bash, remove passthrough.
Set Konsole default command to launch fish, for use as interactive
shell without potential issues that come from being the login shell
Move some configured shell utilities to their own files in shell
directory, stop importing zsh config (replaced by fish)
Move home/ directory under system/ directory. Remove duplicated
machine-specific config files, now handled as one per host (excluding
hardware-configuration directory)
Move as much configuration as possible out of flake.nix and into more
appropriate files (e.g. system/default.nix)
Add a desktop.nix and laptop.nix for system, both will import
home/desktop.nix and home/laptop.nix respectively to reduce
duplication in machine-specific config files
Remove games and streaming directories, moved directly into Vanguard
config file
Remove home/personal.nix since it ended up being empty after changes
Remove old sway config since I haven't been maintaining it and this
refactor will definitely break it
