Fix shortcut keys being blocked by quick chat guard on attack rate bar (#2723)

Resolves #2702

## Description:

This fixes the issue reported in #2702 where certain shortcut keys
stopped working.

The root cause was the shortcut-guard logic introduced in #2528 to
prevent accidental shortcut activation while the quick chat is open.
That logic was also being applied to the attack rate bar
unintentionally, causing shortcuts to be blocked there as well.

This PR excludes the attack rate bar from the quick chat guard so
shortcuts behave correctly again.

## 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
