Flashblocks Behavior

On a Flashblocks-aware endpoint, use "pending" as the block parameter to query preconfirmed state — data available up to 200ms before the next full block is sealed.

Returns a preconfirmed transaction before it is included in a finalized block. Available once the transaction is included in a Flashblock.
