The fork synced to upstream v0.28.0 (element-call #61): matrix-js-sdk
develop with the SDK 44 MatrixRTC changes, delayed-leave delegation.
v0.28 renamed the delayed-leave config keys and its embedded build ships
no config.json (defaults: 18 s). Ship the Lotus values with the build
(build/element-call/config.json -> public/element-call/config.json) so
the desktop app keeps the 60 s grace from element-call lotus #46. The web
deploy keeps the server's own config.json (rsync excludes it); that file
already carries both the old and new keys.
