* Checkout: Allow NFC/LNURL-W whenever LNURL is available
With what we have in master right now, we display NFC only for top-up invoices. With these changes, we display NFC in all cases, where LNURL is available.
Note that this hides LNURL from the list of selectable payment methods, it's only available to use the NFC — and explicitely selectable only for the edge case of top-up invoice + non-unified QR (as before).
Rationale: Now that we got NFC tightly integrated, it doesn't make sense to support the NFC experience only for top-up invoices. With this we bring back LNURL for regular invoices as well, but don't make it selectable and use it only for the NFC functionality.
