libfreemkv 0.31.8: recover unpositioned device key position from an MKB

Browse Source 
Add recover_dk_position: boil a position-less device key down against a
disc MKB to its invariant subset-difference position (node/uv/u_mask_shift)
— zero-descent probe + ancestor walk-up, hoisted verify. Consolidate the
SD-walk surface (drop the research-only probe::walk_pk_against_tables;
make derive_media_key_from_pk_walked internal).
