"About Outpost" in the app menu used to open a separate standalone
window (Window(id: "about") wrapping AboutView). Now just opens Settings
and jumps straight to the About section instead — same content
(AboutInfoView, unchanged), one less window/code path to maintain.
Also removed the "Check for Updates…" button — deferred per explicit
instruction, not deleted for a real reason beyond "not now." A simple
button can come back later; no update-checking logic was ever built; ,
nothing else to clean up alongside it.
