feat: add uConsole CM5 host configuration with Reticulum mesh stack

- New NixOS host 'uConsole' for ClockworkPi CM5 portable terminal
- flake.nix: add nixos-uconsole and nixos-raspberrypi inputs
- Imports: nixos-uconsole.nixosModules.uconsole-cm5,
  nixos-raspberrypi.nixosModules.raspberry-pi-5.base
- Full package list: base tools, HAM radio, SDR/RF, mesh/LoRa,
  security tools, GPS/maps
- Reticulum stack (rns 1.2.9, lxmf 0.9.8, nomadnet 1.1.1) built
  from PyPI via overlays/reticulum.nix
- systemd services: rnsd (Reticulum daemon), kismet (Wi-Fi IDS)
- Kernel modules for SDR (rtl-sdr, dvb) and USB WiFi
- Follows existing host config conventions (cyt-pi as template)
