Refactor DMS IPC bindings for Niri and Hyprland

- Updated `binds.nix` files for both Niri and Hyprland to utilize a centralized `dmsIpcBinds` structure, improving maintainability and consistency across keybindings.
- Introduced `dmsIpcBinds` in `default.nix` for both modules to streamline the command definitions for DMS IPC calls.
- Enhanced `dms` module to define shared IPC commands, ensuring uniform command formatting for different compositors.
