disc: Disc::unlocker_matrix() — registry-driven unlocker report

Returns each registered unlocker's name + whether it applies to this
drive+disc (via the unlock bridge over all_unlockers()). Disc crypto kind
derived in the library so the CLI and autorip render an identical, always-
current report with no hardcoded names. Also adds a Drive::unlocker_name()
runtime getter.
