feat(raid): detect duplicate in-game applications of a confirmed step

An announcement echo that matches a recently CONFIRMED step but no
pending one means the game ran that points command AGAIN — a rapid
re-press inside the log-flush lag, or two officers pressing for the
same item. Previously that second application vanished silently; now it
is flagged in the status bar and appended to dkp-ledger.log as
"DUPLICATE APPLICATION" with the exact command, so the officer can
correct the points in game. Confirmed steps are remembered for five
minutes. Loc x4.
