fix(mship-resources): defer reorder when ADDs are in-flight on existing chat

reorderResources previously only checked pendingPersistResourceKeysRef. When a
chatId exists, addResource fires the POST immediately and only tracks the
promise in inFlightResourceAddsRef — so a reorder before those ADDs settle
shipped a PATCH the server rejected, and the silent catch lost the reorder.

Now treat in-flight ADDs like pending ones: defer the PATCH and replay it
after Promise.allSettled on the in-flight map.
