The "Deactivate account" button should not show up in the primary menu

### Your use case

#### What would you like to do?
Remove the "Deactivate account" button in the primary menu.
#### Why would you like to do it?
Matrix accounts are not one-off things (most of time, I think). The button gives a bad user on-boarding, and for me, it reduces my feeling of security, although it is not very possible to trigger it accidentally because of the confirmation.
#### How would you like to achieve it?
Just move it to some secondary menu.

### Have you considered any alternatives?

No.

### Additional context

Version 0.7.1 (40007012)

### Are you willing to provide a PR?

No

Start by locating the primary menu and the existing "Deactivate account" action in the Android app. Review the requested secondary-menu placement and verify that the button no longer appears in the primary menu while account deactivation remains reachable from a secondary menu.
