chore(3p/sources): bump channels & overlays – xz edition r/7837

Update all 3p/sources as we do normally except

- agenix which is still pinned to 0.15.0

- nixpkgs (unstable) which we bump to the HEAD of the staging-next
  branch. This branch includes the downgrade of xz from 5.6.1 to
  5.4.6 (https://github.com/nixos/nixpkgs/commit/d6dc19adbd). It
  also includes the second haskell-updates rotation with GHC 9.6.4
  which contains a few build fixes that seem to be required to get
  our Haskell targets to work.

Note that this only reverts xz to a version that doesn't contain the now
known backdoor (CVE-2024-3094) which may or may not actually affect
NixOS. Additionally reverting to a version before the malicious
contributor's involvement may be difficult, but prudent:
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=1068024

Changes required by the updates:

- //3p/overlays/haskell:

  - Update ihp-hsx to latest master to fix build with Stackage LTS 22.
  - Update tmp-postgres to latest master to work around failure with
    ansi-wl-pprint >= 1.
  - Patch punycode for mtl >= 2.3.

- //users/Profpatsch:

  - Clean up some warnings, mostly about unused dependencies
  - my-prelude: Fix build with ghc-boot-9.6.4
  - cas-serve: Use crypton over unmaintained cryptonite
  - ical-smolify: skip in ci, iCalendar would require heavy patching to
    work with Stackage LTS 22.

- //users/{wpcarro,aspen,flokli}:

  Disable home-manager / nixos configuration builds that seem to have
  transient failures that should disappear as we move away from
  staging-next and closer to an actual channel release.
