Give feedback whether the password is correct without ending the call

[nickvergessen]

Steps to reproduce

1. Share by mail and set the password via the talk option
2. Open the link
3. Start having the call
4. Try the password the owner told you

Actual behaviour

🛑 The call ends immediately because the side reloads.

Expected behaviour

✔️ Password is verified
🗯️ Recipient should have the option to say "Thanks the password worked"

Idea

We can verify the password without sending the user to the file already.
In case it is correct, we show a button End call and continue to the files
