This PR ensures that:

• Opening and closing the sidebar animates smoothly
• If an org has no teams, there's no divider
• The settings menu doesn't conflict with the text on the task cards

Things to note:

• I reduced the width of the Add Meeting button slightly. It's still wider than prod, but narrower than it was.
• The three-line long team name is an edge case. A team name with the max characters allowed is usually 2 lines, but if the characters are particularly wide, e.g. 3 instead of i, it can take up three lines. I'm hesitant about changing the padding without a review from @ackernaut, so I'd prefer to merge this.
• I also like your point about removing the menu. I think Terry could see how it feels in production and decide whether to keep/remove it.

awesome! yeah, team name length is an edge case for sure, i'll get it on staging & give it a go!
