Rich text editor does not take full width or height of the screen

This issue respects the following points:

• I have read the FAQ
• I have searched for existing issues
• The issue affects the Notes Android app, neither the Notes server app nor the Nextcloud Android app.

Describe the bug

The rich text editing area does not expand to use the full width or full height of the screen. There appears to be unused space on the right side and at the bottom when scrolling down, which reduces the usable editing area. The server background is then visible.

Expected behavior

The editor should take 100% of the available screen width and height (excluding system UI elements like status/navigation bars), maximizing the usable editing space.

Stacktrace

No file or test is named. First reproduce the layout problem on the reported Android setup and trace the rich text editor's screen layout; done when the editing area fills the available width and height while excluding system UI, without exposing the server background.
