[nix-deck] Use NixOS unstable for better Jovian compatibility

- Switch nix-deck to use nixpkgs-unstable and unstable home-manager/plasma-manager
- Remove jovian-compat.nix shim (not needed on unstable)
- Add bitwarden-desktop compatibility overlay for stable/unstable coexistence
- Update hardware-configuration.nix with actual Steam Deck hardware detection
- Add 8GB swap file configuration
- Configure AMD CPU microcode updates

This allows nix-deck to work with the latest Jovian-NixOS while keeping other
machines on stable 25.05.
