Introduces a greg.nebula NixOS module and enables it across all managed
hosts for the nebula.thehellings.com overlay (CIDR: 10.157.0.0/16).

Architecture:
- linode: lighthouse + relay (public internet, UDP 4242)
- genesis: regular node + unsafe_routes router for 10.42.0.0/16 (home LAN)
- hosea, isaiah, jeremiah, zeke, exodus: regular nodes with unsafe_routes
  pointing to genesis to reach the home LAN

Changes:
- modules/nixos/nebula.nix: new greg.nebula module
  - isLighthouse / isRelay options
  - unsafeRoutes option (tun.unsafe_routes)
  - routesSubnet option: enables IP forwarding + nftables masquerade NAT
    on the gateway host (genesis) so Nebula peers reach 10.42.0.0/16
  - agenix secret reference per-host (secrets/nebula/<name>.key.age)
  - opens UDP/4242 in the firewall
- modules/nixos/default.nix: import nebula.nix
- hosts/unstable/linode/default.nix: greg.nebula.isLighthouse = true
- hosts/unstable/genesis/default.nix: greg.nebula.routesSubnet = "10.42.0.0/16"
- hosts/unstable/{hosea,isaiah,jeremiah,zeke,exodus}/default.nix:
  greg.nebula.enable = true with unsafeRoutes via genesis
- network.json: add nebulaIp field for each managed host
- secrets/secrets.nix: declare nebula/<host>.key.age entries
- secrets/nebula/README.md: full PKI bootstrap guide (CA, certs, agenix)

root 8e218a71e0 fix: add missing shire-zebra.ts.net DNS entries; update exodus Tailscale IP
buildbot/nix-eval Build done. (1 warning)
buildbot/nix-build Build done.
genesis, zeke, linode, and exodus were missing shire-zebra.ts.net
aliases in the genesis dnsmasq hosts file. Only hosea, isaiah,
jeremiah, gitlab, matrix, chronicles, and nas1 had them. Since
genesis is the DNS server for the whole network, Prometheus (and
everything else) couldn't resolve those four hostnames, causing
instant connection failures on scrape.

Also update exodus Tailscale IP from 100.80.99.48 to 100.70.99.91
(stale IP in both network.json and the hosts file).
