chore(3p/sources): bump channels & overlays (2025-02-09)

Included changes:

* targeted primary NixOS channel back at `nixos-unstable`

* //3p/chicago95: disable new broken symlink check

* //tvix: omit unnecessary lifetime clippy recommends

* //users/sterni/blipqn: wait a bit for data to arrive in test so it
  succeeds under load.

* //fun/paroxysm: force pkg-config flag of pq-sys by adding a bogus
  dependency on it. Otherwise, pq-sys will try to use pg_config
  which does not work correctly in pkgs.libpq at the moment.

* //users/flokli/keyboards/dilemma: disable temporarily
