fix(focil): use fork choice head_hash for IL production

Browse Source 
In ePBS/Gloas, the execution payload is delivered via envelope, not
embedded in the beacon block. produce_inclusion_list was trying to
extract parent_hash from the beacon block's execution payload (which
doesn't exist), causing every IL fetch to fail.

Use cached_head.head_hash() which correctly tracks the execution
block hash through fork choice, including envelope imports.
