feat: Add host sydpc

My, this is a lot TwT. Much work was batched as part of the transition from guix-rebound to nixos-testbed/sydpc. - Discord/Vesktop module & config. - Syncthing setup. - Assorted Emacs changes. - Waybar config. - Niri config. - Steam config. - Some MPD. - Stylix config. - Files/Impermanence things. - Enable Ghostty. - God knows what else.
