Fix Small Backend Issues — Laravel 12 / PHP 8.4 Logistics App

I need a sharp eye on a few nagging issues in our live logistics platform. The app runs on Laravel 12 / PHP 8.4 with MariaDB 11, Redis, MongoDB, and Docker, and overall it’s solid—these are just the last bits keeping the code from looking as good as it runs.

Here’s what I want delivered:

• Refactor the BHX number generator. Right now the logic is duplicated in three places and wastes up to a thousand look-ups each time it runs. I want a single, clean method that pulls the next number with one efficient query.
• Remove four clearly tagged pieces of dead code—two deprecated methods and two unused routes labeled “will not use.” Please confirm nothing else references them before you delete.
• In FuelImport.php there is a hard-coded Excel column index with a TODO beside it. Make that value dynamic so the import works regardless of column order.
• BidApi is spewing a “CHECK THIS” log because the vehicle-haul attachment was never finished. Close that loop so the log stays quiet.

All work must respect the existing stack and go through our normal Docker setup; Laravel Pint, PHPStan and Pest already run in CI, so your changes should pass those gates.

Send me a fixed price for the whole job, a quick line about similar refactors you’ve done, and the earliest you can start. I plan to choose fast and get this merged immediately after review.
