fix: group packs on everything that shapes them

group_identical_platforms fingerprinted each file by destination, sha1 and md5. Two platforms whose lists differed only in required, zipped_file, size or crc32, or in how the frontend checks a file, would have shared the representative's pack and verify result. The fingerprint now carries every field of every entry and the platform's verification_mode and hash_rule. No current platform is regrouped.
