hainich: hacky version of thelounge as webchat

Intended for KontraIAA; requirements were that it should be a simple and
non-confusing as possible.

I tried both KiwiIRC and thelounge, and found both horrible to
package (a fact not helped by the somewhat opaque structure of
nixpkgs.nodePackages, which does contain a version of thelounge but
will apparently ignore overrides of the src attribute).

Instead, this now contains a very hacky version of thelounge, which
merely takes the already-built version from nixpkgs and glues some extra
css to it which hides potentially confusing fields.

Things hidden on the "connect" screen:
 - the "name" field (since thelounge offers "nick" "name" and "realname"
   by default, which seems too much for something embedded on a website)
 - the "I have a password" checkbox

Things hidden on the general view:
 - the button to open the side panel (the panel itself is not hidden,
   and will appear by itself on wider layouts), so that users will only
   see that one channel
 - the "channel options" menu (which includes a "leave channel" option
   which would effectively break the webchat)

Things not addressed:
 - thelounge has autocompletion for /join /leave, etc. Do we want to
   disable that as well?
 - It would probably useful to suppress all the "x joined the channel"
   messages. Thelounge supports this, but apparently doesn't support
   setting it as default?

Misc:
 - for now, users will be connected to #thelounge on libera.chat, which
   appears to be okay with being used as an experimental channel
 - I allowed prefetching link previews, but only on the server's side
   (i.e. users' browsers won't fetch content from arbitrary sites)
 - not yet tested on hainich, but should work (tested in a NixOS
   container)
 - currently assumes a "webchat.voc.hacc.space" domain (I think we had a
   voc domain? but I forgot where it is …)
