Users can bid in the same block when the actionEnd could be called (`block.timestamp==actionEndTime`), depending on the order of txs in block they could lose funds

The protocol doesn't properly treat the `block.timestamp == auctionEndTime` case. Impact: High - There are at least two possible impacts here: 1. By chance, user bids could land in a block after the `auctionEnd()` is called, not including them in the multiplier calculation, leading to a situation where there are insufficient funds to pay everyone's claim; 2. By malice, where someone can use a script to call `auctionEnd()` + `bid(totalBids)` + `claimTokens()`, effectively depriving all good faith bidders from tokens. Likelihood: Low – The chances of getting a `block.timestamp == auctionEndTime` are pretty slim, but it’s definitely possible.
