Fix wrong auth token key and mislabeled loading dialog on payment flows

registration/success read the token from the wrong localStorage key
(token instead of hope_events_token), which broke registration/form
loading there and made the new "Pay with Yoco" checkout call fail with
"Not authorized, token failed" — switched to the shared auth context
like the rest of the app.

dashboard/user's "Make payment" reused the ticket-email dialog, which
hardcoded "Sending tickets…" while loading — the dialog now takes an
optional loading title/subtitle so payNow can show its own message.
