Thread templates, record audio & video

We're super excited to finally release this work.

Thread templates follows on from the success of proposal templates released in July this year.
It allows you to use a predefined template to start a thread, helping you create a better context for your readers, and make repeatable workflows for your group processes.

Record audio & video messages
By popular request, you can now record an audio message directly into your comment, discussion context, poll or vote. If you have an OpenAI api key on your server, then a transcription of the message will appear under the recording after you save it.

Video messages are supported too, but there is no automatic transcription. We may even remove video message recording by default, as Safari cannot open videos recorded by Chrome and Firefox currently. Blame Apple for this.

Other minor stuff:

Closing a thread will now lock the thread so no new comments, edits, or changes can be made to the thread.

Immediately after inviting a person to your group, you can add invite them to polls. This means you don't have to wait for people to accept their invitations before starting discussions or proposals. However these people will need to accept the invitation before more notifications arrive.
