chore(3p/sources): Bump channels & overlays

* agenix has not been updated (https://github.com/ryantm/agenix/pull/241).
* wasm-bindgen bumped to 0.2.92 in Rust WASM projects
* 3p/lisp: port lispPackages from stable channel

  The Lisp package set we are using (`pkgs.lispPackages`) is the "old
  old" package set, whereas we were supposed to have been using
  `pkgs.lispPackages_new` (which is the "old new" package set).

  Either way we missed that train, and now there's a "new new" package
  set, but with a twist: Lisp packages in nixpkgs are now tied to
  their compilers, so the most generic way to access them seems to be
  from `pkgs.sbclPackages`.

  Switching to the packages from the "new new" package set doesn't
  work: Lots of stuff stops building if we just switch the sources
  over, and not everything is trivially fixable.

  For now we stay on the lispPackages from the stable channel. We need
  to look into the migration later.

  Or rewrite panettone.
* tvix: update generated protobuf files
* 3p/nixpkgs: pick trunk from stable channel; newer versions try to
  read files and do network I/O during build, but don't print enough
  details in error messages to figure out why.
* 3p/overlays: remove tdlib override (nixpkgs is currently new enough)
* 3p/overlays: override telega.el sources while updates are lagging in
  nixpkgs
* users/flokli/ipu6-softisp: update firmware paths, which NixOS now
  stores zstd-compressed.
