Fixes Alt+Enter fullscreen

[KoopaCode]

Description

Fixes fullscreen save so both F11 and Alt+Enter work the same.

Changes

• Alt+Enter now saves fullscreen state the same way F11 does.
• Fullscreen now comes back on next launch no matter which key combo was used.

Previous Behavior

Fullscreen only saved correctly when using F11.

If you used Alt+Enter, it went fullscreen for that session, but it did not stay fullscreen next time you launched.

Root Cause

There were two different fullscreen paths.

F11 saved the setting, but Alt+Enter did not save.

New Behavior

Fullscreen now saves and restores correctly for both F11 and Alt+Enter.

Fix Implementation

Made Alt+Enter use the same save path as F11.

• Both toggle methods now go through the same fullscreen update logic.
• Fullscreen state is written when either method is used.
• No other fullscreen behavior was changed.

Yes, that was my mistake, sorry. I completely forgot that you could also do that with Alt+Enter.

Would it make more sense to, instead, observe if the Fullscreen state has changed for any reason, then write it? Seems better than relying strictly on binds.
