Add DMS plugins for rbw lock and wvkbd toggle

- Introduced new DMS plugins: `rbw-lock-toggle` for managing Bitwarden vault state and `wvkbd-toggle` for showing/hiding the on-screen keyboard.
- Updated `flake.lock` and `flake.nix` to include the new plugins and their configurations.
- Removed legacy options and files related to the rbw lock toggle, streamlining the DMS configuration.
- Enhanced the home-manager module to support the new plugins and their integration into the DMS environment.
