Thore Cimbal 88c4e155ce Merge upstream v1.12.26 - reconnect the fork to Element Web (management #0099)
The repo had no upstream ancestry: a whole tree arrived in one commit in May, so
every update meant re-applying our patches by hand onto a fresh checkout, and a file
Element moved would take our lines with it silently.

The real base was found by measuring tree distance across develop rather than trusting
the changelog: deadd548, not the v1.12.17 tag. With that set as a temporary graft, this
merge computed as a proper three-way merge - 32 conflicts instead of 1757.

Resolutions, each decided rather than defaulted:

- 24 GitHub workflows stay deleted; we build on GitLab CI.
- MImageBody.tsx is gone upstream, migrated to MVVM. Our ClamAV error label moved into
  ImageBodyViewModel.computeErrorLabel, ahead of the DecryptError branch, matching what
  VideoBodyViewModel and FileBodyViewModel already do.
- Upstream extracted the room list item body into RoomListItemContent. Our call
  participants list and its getInitials helper moved there; both sides' CSS classes and
  both sides' props are kept.
- matrix-js-sdk follows upstream at 42.2.0 - our git ref pin was a workaround for a
  stale ref, and following upstream is the point of this merge.
- Element Call stays ours. Checked before deciding: @element-hq/element-call-embedded
  is referenced nowhere in the tree, while webpack.config.ts needs
  @sorb/threadnet-call-embedded, so taking upstream's line would have deleted the noise
  suppression from #0054 without a word.

The lockfile was regenerated with pnpm 11.20.0, which upstream now requires through
devEngines. CI already runs corepack enable, and onFail: download makes it fetch that
version by itself.

Not yet accepted: this needs a build and the ClamAV functional test - send an encrypted
file, receive a rejected one - before it goes near main.
