Single-retry was still flashing slots empty on the inventory when lag
exceeded 0.25s — the retry pass would read nil and broadcast the empty.
Track a per-slot retry counter (capped at RETRY_MAX=12, ~3s) so we keep
deferring until the link comes back or we hit the ceiling. Bank was
never affected — it goes through PLAYERBANKSLOTS_CHANGED, not BAG_UPDATE.
Under server lag BAG_UPDATE can fire before item data arrives, causing
GetContainerItemInfo to return nil for a still-occupied slot and Bagnon
to broadcast ITEM_SLOT_UPDATE with no link — the slot then renders empty
until the next bag event. UpdateItem now queues a single ~0.25s retry
for the bag when a previously occupied slot reads nil; the retry pass
trusts whatever it reads, so genuine empties still resolve.
