ediblerope 34a45af357 flake: split mediaserver onto nixos-25.11, keep desktops on unstable
The mediaserver kept hard-freezing on local builds (gnupg, openldap,
deno/rusty-v8) whenever a fresh unstable revision outran Hydra's
binary cache. It doesn't need bleeding-edge packages — every service
it runs is mature enough that 6-month-old versions are fine — so move
it onto the stable channel where the cache is essentially always
warm. Gaming and Macbook stay on unstable for fresh GPU/kernel work.

Implementation: add nixpkgs-stable + home-manager-stable inputs,
parameterise mkHost to accept a (nixpkgs, home-manager) pair.

Drive-by:
- Switch homepage.nix from environmentFiles (plural, unstable-only)
  to environmentFile (singular, present on both channels).
- Gate the openldap-skip-tests overlay to non-mediaserver hosts so
  it doesn't force a local rebuild on stable, where openldap is
  always cached.
