style(cashu): make wallet settings danger zone red

Match the main Settings screen's danger styling: the "Danger Zone" header and
the Stop-nutzaps / Delete-wallet rows now use colorScheme.error for the header
text, row title, and leading icon. Reuses the shared R.string.danger_zone
instead of a duplicate cashu-specific string.
