core/types: fix CopyHeader missing BlockAccessListHash deep copy

Browse source 
CopyHeader copies all pointer-typed header fields (WithdrawalsHash,
RequestsHash, SlotNumber, etc.) but was missing the deep copy for
BlockAccessListHash added by EIP-7928. This caused the BAL hash
to be silently shared between the original and the copy, leading
to potential data races and incorrect nil-checks on copied headers.
