Refactor flake.nix and add key remaps script

- Refactor `flake.nix` to simplify the `outputs` section and remove redundant configurations
- Update `lsp.nix` to use hostname for NixOS and Home Manager configurations.
- Add `key-remaps.nix` script to `dwm` configuration and update `xinitrc.nix` to include it in autostart.
- Comment out non-functional `displayManager.sessionCommands` in `citadel/default.nix`.
