Build a joined cryptography inventory

Runs the cipher inventory and the post-quantum TLS readiness inventory together so that every finding lands in one Cryptography inventory data table. Findings that different detectors report at the same source location — a TLS entry point classified both for the protocol versions it allows and for the key-exchange groups it offers — are joined into a single row there, which the per-detector tables cannot express. Those per-detector tables are still emitted unchanged, carrying the same findings unjoined. Changes nothing.
