[Feature Request] Show total messages that would be deleted when deleting all messages for a user

[watzon]

Is your feature request related to a problem?

Accidental deletion and banning of users that have been around for a while

Describe the solution you'd like

Several telegram clients, like TGX, show a count of messages that would be deleted if you choose to delete all messages for a user.

Describe alternatives you've considered

You can, of course, now check the message history of a person, but it's nice to have an extra failsafe.
