Clear ID_INPUT_JOYSTICK on the Keychron keyboard (3434) and X3PRO mouse
receiver (3151) so Steam/games stop grabbing them as a phantom controller.
Also grant the active session uaccess to those devices' hidraw nodes via a
60-*.rules package file (must sort before systemd's 73-seat-late.rules) so
their browser-based WebHID configurators work.

Add the nix-flatpak flake input and wire its NixOS module into the gaming
module to declaratively install io.mrarm.mcpelauncher from Flathub. The
Flatpak build tracks the newer, pairip-protected Bedrock releases ahead of
the nixpkgs mcpelauncher package.
