[Backport release-25.05] fractal: 11.2 -> 12

[nixpkgs-ci]

Bot-based backport to release-25.05, triggered by a label in #432916.

• Before merging, ensure that this backport is acceptable for the release.
  • Even as a non-committer, if you find that it is not acceptable, leave a comment.

Because of the important security patch that this upgrade provide, https://matrix.org/blog/2025/08/security-release/ , would it be possible to review and merge it soon?

[LeSuisse]

This needs some work, can a maintainer take over?

I'm going to close this for now, until when/if we get a newer rustc in 25.05. Easy to re-open then.

OK. Just for information, Element company is saying they will update all their rooms to v12 in septembre, so, users on stable won't be able to use fractal passes septembre.
