feat: staker upgrade to include protocol fees

[sandybradley]

Request has been made to include protocol fees in the Staker contract. An upgrade before any staked validators would make this easy. Although we have to wait 7 days after committing, to finalize the update on mevETH.

Will have this deployed by end of day tomorrow

@sambacha pls share the contract address once deployed

We can review this again @sandybradley now that Decun has landed on mainnet in addition to any other changes as it relates to the new beacon state balance access we have

Yes. Decun includes eip-4788 which in theory lets us unpack CL validator balances. We can create a view function for reward visibility. We may be able to tie this in with automating rewards.

Also worth mentioning we can automate exits via execution layer when eip-7002 comes out.

These upgrades should probably be in a separate PR as this one has finished its purpose.
