payout: fail review when a money line lands on collapsing LogPrint

scripts/check-money-log-lines.sh flattens each LogPrint call in
src/rpc.cpp and fails if a money-moving phrase appears in a plain
LogPrint call. A new line that reports money moving needs
LogPrintAlways and one more phrase in the list.

+# Money-moving payout lines must print every time they fire: they are the
+# audit trail for obligations created, moved and destroyed, and LogPrint's
+# burst collapse can stand one line in for any number of events inside one
+# 3-second window (issue #3: 100 voids totalling 4,950 BTF read as one
+# 49.49 BTF line). Every line carrying one of the phrases below must use
+# LogPrintAlways, which keeps the category gate but skips the collapse.
+#
+# Adding a payout line that reports money moving? Use LogPrintAlways and
+# add its phrase here. A phrase found in a plain LogPrint call fails this
+# check; anything else passes, so a non-money line is never held up by it.
