[BUG] maximize-to-edges windows don't respect struts for spacing

[aloop]

Submission checklist

• I have searched existing issues and confirmed this is not a duplicate.
• I am using the latest release or a recent build of main.
• I confirmed this happens in Umbriel itself, not in a desktop shell, a portal backend, or a single application.
• I checked whether my configuration causes it, for example by reproducing with the packaged examples/config.toml.

Bug description

When struts are configured, spacing between maximize-to-edges windows and other windows does not seem to calculate the spacing including the struts. I'm unsure if this is applicable to other layouts as I only use scrolling.

Steps to reproduce

1. Enable struts, I have a gap of 8 and left/right struts set to 16
2. Open a window and maximize-to-edges
3. Open a second window
4. Windows will clip into one another

Expected behavior

maximize-to-edges windows should not overlap with other windows

Actual behavior

maximize-to-edges windows overlap with other windows
