Always copy seed DB from assets, VACUUM seed to reclaim space

Browse source 
Size comparison was unreliable — SQLite reuses free pages internally,
so adding products didn't change file size. New seed never copied.
Now: always overwrite on every launch (~8MB, <1 sec).
VACUUM reduced seed from 8.5MB to 8.2MB.
