refactor: quality audit fixes, honest verification reporting

- batocera_scraper: fix OrderedDict parsing for ast.literal_eval
- auto_fetch: fix TypeError when sha1/md5 is None
- verify: filter non-ZIP files for zipped_file entries (F2)
- verify: distinguish ZIP read errors from hash mismatches (F5)
- generate_pack: track seen_destinations with source hash (F7)

Batocera ep64/ep128.zip now correctly reported as MISSING
instead of false UNTESTED (resolved to .rom instead of .zip)
