misc whisperback improvements
Closes #19997 (closed), #19351 (closed), #20040 (closed)
Screenshots:
Notes:
- I did manual testing
- It might seem from the screenshot that strings are not translated, so #20040 (closed) seems to still be there. But actually, only new strings are still in English (obviously those aren't translated). I tested that it actually does the job, as is visible in some part of the interface
