Invites don’t tell you when they arrived

### Steps to reproduce

1. Get invited to a room
2. See it in the room list
3. Feel wrongfooted that you don’t know when it arrived
4. Have to guess based on the adjacent roomlist entries.


for instance, i’m going to guess this invite is from thursday. But if it was newer, i’d have to entirely guess if this is a brand new invite or hours old

### Outcome

#### What did you expect?

timestamps on the roomlist entries like any other

#### What happened instead?

uncomfortable absence of info
