unlock_bridge: run_features/run_bus dispatch; report LibreDrive vs Renesas

Adopt freemkv-unlock's split Unlocker trait: run_features drives the drive-prep capability, run_bus the content bus removal, each iterating unlockers until one doesn't decline (NotApplicable = try next; Ok or a real error stops).

unlocker_matrix now reports which drive-prep unlocker actually ran — LibreDrive removes the bus at the drive; Renesas unlocks features but leaves the bus to the cert. Wire product_id through to fu::DriveId.

Bump to 1.2.3.
