Make DA height on BitcoinLightClient trustless

[eyusufatik]

This is sort of a research question.

Right now we are "initializing" the BitcoinLightClient contract with a number and hash given by the sequencer, this is fine for full nodes, as they pull the blocks themselves and supply the hash to the STF themselves. But on the batch proof this is a problem as bitcoin block headers does not include a block number.

One simple solution is to hard code the height and hash in Citrea genesis just like #1151.

There might be better solutions so leaving that as decision needed for now.
