fix: align status terminology with Batocera source code

Batocera uses exactly 2 statuses (batocera-systems:967-969):
- MISSING: file not found on disk
- UNTESTED: file present but hash not confirmed

Removed the wrong_hash/untested split — both are UNTESTED per
Batocera's design (file accepted by emulator, just not guaranteed
correct). Fixed duplicate count bug from rename. Reason detail
(MD5 mismatch vs inner file not found) preserved in the message.

Verified against Batocera source: checkBios() lines 1062-1091,
checkInsideZip() lines 978-1009, BiosStatus class lines 967-969.
