Matthew Jackson 946632d9fb Restore AACS PK key-processing path in keysources

unit_keys_from now resolves the Media Key in order: stored per-disc MK
-> keydb Processing Key pool (mk_from_pk vs this disc's own MKB) ->
device-key pool (mk_from_dk), then MK+VID -> VUK -> UK. MK/VUK entries
still honored directly; cross-disc MK-pool brute stays retired. Fixes the
factually-wrong justifying comment + adds PK-pool KATs.

Changelog

[1.1.0-beta.1] — UNRELEASED

Fixed

Processing-Key decryption restored. A keydb Processing Key is again driven through the full AACS chain — PK → Media Key (against this disc's own MKB) → Volume Unique Key (with the disc Volume ID) → unit keys — so discs that ship only a Processing Key decrypt again. Stored Media Keys and Volume Unique Keys are still honored directly. (Cross-disc Media-Key reuse remains intentionally disabled.)
