Pop a toast when a participant tries to move ahead of the meeting facilitator

Issue - Enhancement

When a meeting participant tries to navigate ahead of the facilitator, presently the click falls into a void. For example, when a participant tries to click on an agenda item while the facilitator is still in Project Updates. It can sometimes feel like our app is broken.

I suggest we pop a toast when this happens to that participant that reads:

Hold your horses! 🐴
You'll have to wait for the facilitator
before you can go there.

This popped up in #578.

Here's what I think happened:

1. The facilitator started the meeting but never ended it
2. A second user logged in to try and use Action (probably to use the team dashboard) and they see that a meeting is active
3. They join the meeting with the intention of ending it but they can't (without knowing the secret incantation)
4. Most importantly, the user didn't even realize they were not the facilitator - it just look like our software was stuck

Super frustrating!

In addition to this bug, what to do? Brainstorming options (in addition to the above):

1. If a meeting has been active for >24 hours, end it automatically (requiring a server task)
2. Add a button to the team dashboard modal offering to end a meeting if it has been active for > 24 hours
3. Add a button to the meeting sidebar for the same
4. Other?

I'll open a separate issue to track.
