Updates translated strings in web/ that do not need updates to any
tests. The majority of these strings are also unique to the file/
template that they are in. A few have overlap with one other file.
Some changes here update placeholders/variables in these strings to
no longer use stream so that all the translation updates for this
rename happen at the same time.
The exception to this are cases of "<z-stream>" placeholders in
these translated strings.
Part of the stream to channel rename project.
Adds a loading spinner to the message history overlay,
improving the user experience by providing visual feedback while the
message edit history is loading.
We redesign the message history modal to make it look similar to the
drafts and scheduled messages, using the shared styling/rendering
logic for that those existing elements to have a less goofy widget.
Fixes#28695.
