PROPNOTES - ORDER REFERENCE HOSTING HOTFIX V6.4

The supplied database export was checked and is structurally correct.
This hotfix addresses live hosting accounts that cannot write either database
sequence store even though the required schema exists.

INSTALLATION

1. Back up the current /asap/config.php file.
2. Upload config.php from this ZIP directly to /asap/config.php.
3. Overwrite the existing file.
4. No SQL import is required for this hotfix.
5. In Admin > Products, confirm the product's Order ID Prefix is EUR, GBP,
   USD or the value you want. Products saved as ORD will continue to use ORD.

Additional checkout in that same second: EUR-260828-110000S1

The hotfix tries the dedicated database sequence first, then the existing
settings table, and finally an atomic locked file under:

/asap/storage/order-sequences/current.json

The file is created automatically. No random suffix is ever generated.
