P1 Badge Accept parent bids when enabling boundary reorgs

For a Gloas proposer reorg at the first slot of an epoch, this now selects the weak head's parent, but isBidCompatibleWithHead() in packages/beacon-node/src/chain/validation/executionPayloadBid.ts:63-66 still rejects every bid building on that parent when bidSlot is an epoch boundary. Because both gossip and API bid validation use that predicate, no matching bid reaches the pool queried during block production, forcing the proposer to discard valid builder bids precisely when this new reorg path is taken.

Useful? React with 馃憤聽/ 馃憥.
