feat: add uConsole CM5 host configuration

- Add nixos-uconsole and nixos-hardware inputs for CM5/RPi5 support
- Create hosts/uconsole/configuration.nix with HAM radio, SDR, and security tools
- Create hosts/uconsole/hardware-configuration.nix for CM5 hardware
- Register uConsole in flake.nix nixosConfigurations
- Add uconsole host key placeholder to lib/keys.nix

 ## Progress
 
-**Merge Priority Order** (CRITICAL - merge in this order):
-
-| Priority | PR | Description | Status | Notes |
-|----------|-----|-------------|--------|-------|
-| 🚨 1 | #28 | **Security hardening** (firewall, fail2ban, SSH) | Open | **MERGE FIRST** - protects all other services |
-| 2 | #22 | Matrix bridge dependency fix | Open | Blocks Hermes functionality |
-| 3 | #21 | Backup network creation fix | Open | Infrastructure fix |
-| 4 | #25 | Hermes voice GPU support | Open | Feature enhancement |
-| 5 | #24 | uConsole CM5 host | Open | New hardware support |
-| 6 | #23 | NixOS deployment infrastructure | Open | Deployment tooling |
-| 7 | #1 | AI worker restricted access | Open | Legacy PR (superseded by hardening) |

 **Execution Order:**
-Phases execute in numeric order: 1 → 2 → 3 → 4 → Security → 5 → 6 → 7
-
-**Merge vs Phase Execution:**
-- PRs can merge independently (no strict phase ordering for merges)
-- **EXCEPTION:** Security hardening (#28) must merge before any new services are exposed
-- After security merge, deploy with: `nh os switch --flake .#lazyworkhorse`
