## Description:
Adds a `confirmBeforeClose()` override to `JoinLobbyModal`, matching the
existing behavior in `HostLobbyModal`.
Because the german streamers had a lot of problems with accidentally
leaving today.
When a user is in a lobby and tries to close the modal (Escape key or
clicking outside), they now get a confirmation dialog asking if they
really want to leave. If the user hasn't joined a lobby yet (still on
the join form), the modal closes without prompting.
Reuses the existing `host_modal.leave_confirmation` translation key.
## Please complete the following:
- [X] I have added screenshots for all UI updates
- [X] I process any text displayed to the user through translateText()
and I've added it to the en.json file
- [X] I have added relevant tests to the test directory
- [X] I confirm I have thoroughly tested these changes and take full
responsibility for any bugs introduced
