frontend: add support for showing raised hand

[silbe]

We were puzzled that the /raise / /unraise commands had no effect and figured out the frontend simply ignores the raisehand status. This MR adds support for showing the hand-paper symbol (looks like a raised hand) instead of the circle symbol in the user list whenever a user raises their hand.

Is there any test for the frontend code that I should adjust?

Applied in 993d664, with a tweak to get proper typing. (In the future, please check your changes with Typescript.)

Thanks for fixing my mistake! How can I perform the Typescript check myself? If I just run tsc (from node-typescript in Debian Bullseye) from inside the static directory I get a whole bunch of errors:

What version of typescript ? Mine is

$ dpkg -s node-typescript | grep Version Version: 4.5.4+ds1-1

I was using 4.1.3-1 from Bullseye (current stable). 4.5.4+ds1-1 is from Bookworm (current testing) but is installable in Bullseye. With that version there are no errors, thanks!
