imgui: 1.91.4 -> 1.92.7

[jemand771]

Changelog: https://github.com/ocornut/imgui/releases
Diff: https://github.com/ocornut/imgui/compare/v1.91.4..v1.92.7

Update imgui to v1.92.7 and fix any breakage caused by it. Included patch for dartsim is merged by upstream but still unreleased, patch for imtui is not merged and so far unreviewed. Maybe someone from nixpkgs can take a quick look there: ggerganov/imtui#62

Supersedes:

• imgui: 1.91.4 -> 1.92.3 #444588

Depends on (wait for merge):

• comaps: 2025.11.07-2 -> 2026.03.23-5 #504172
• implot: 0.16 -> 0.17 #472954
• imnodes: unstable-2024-03-12 -> unstable-2025-06-25 #505138

ignore my branch name, 1.92.7 came out while I was waiting for other things to settle / get merged

we should add ?full_index=1 to github .patch urls: https://github.com/NixOS/nixpkgs/blob/master/pkgs/README.md#fetching-patches

otherwise diff lgtm

@nim65s as far as I understand it, that only applies to fetchpatch2, not fetchpatch.
on that note, I'm not really sure when to use which one (the 2 seems to imply "newer" and "better", but it's used almost nowhere) - I can switch over (and add full_index=1), if there's a reason to

[nim65s]

Yes, the situation is not super clear. I guess we can dismiss my comment here
