core/txpool: disallow future churn by remote txs (#26907)
Prior to this change, it was possible that transactions are erroneously deemed as 'future' although they are in fact 'pending', causing them to be dropped due to 'future' not being allowed to replace 'pending'. 

This change fixes that, by doing a more in-depth inspection of the queue.

core/txpool: implement additional DoS defenses (#26648)
This adds two new rules to the transaction pool:

- A future transaction can not evict a pending transaction.
- A transaction can not overspend available funds of a sender.
