Follow-up to the previous commit — page.tsx now passes
default_qr_logo of type "wownero" | "monero" | "none" | "custom" to
this component, but the prop was still typed as the narrower
"monero" | "none" | "custom" set. Next build failed with TS2322.
Widened initialLogo prop + the internal useState + buildInitialState
helper to match.
