bolt12-test: committed regtest offer/invoice fixtures instead of a vanished scratchpad

The default fixture paths pointed into an old session's scratchpad, so the
test died reading them (exit 1, no output). Fresh pair from the regtest stack:
offer from clc, invoice fetched by cln-ark. Network and expiry checks no longer
assume mainnet or a recent wall clock.
