fix: case-insensitive MD5 lookup in resolve_file

Browse Source 
Recalbox uses uppercase MD5 hashes (6E3735FF...) but database index
is lowercase. Added .lower() to MD5 lookups in resolve_file().

Fixes scph101.bin wrong variant in Recalbox pack (was picking
.variants/ copy instead of primary due to MD5 case mismatch).
