Request: Bring back the "Sign out" button or rename "Remove this session" for better user clarity

### Your use case

Description

The recent Element Web interface uses "Remove this session" instead of the previous "Sign out" option.

While technically correct from a Matrix session perspective, this wording is confusing for regular users. Most users understand "Sign out" or "Log out" as the action to leave their account on the current device or browser.

Current behavior

Users need to go to:

Settings → Security & Privacy → Sessions → Remove this session

to log out from the current session.

Expected behavior

Please consider bringing back the "Sign out" button, or use a clearer label such as:

Sign out
Sign out this device
Sign out (Remove this session)

This would make the interface easier to understand, especially for organizations deploying Element Web to non-technical users.

Impact

For self-hosted Matrix deployments and organizations with many users, the current wording may cause confusion because users may not realize that "Remove this session" is the logout function.

Thank you for considering this usability improvement.
