Fix transfer quantity, unify date format, align demo seeds

Stock Transfer list showed 0.00 (read in instead of out); stock-out/transfer forms show the location quantity; dates display as YYYY-MM-DD HH:mm:ss. Demo seeds map product accounts, use product names and supplier batches, and add demo_seed_assets.php.
