Enhance Core PHP Driver Page

My Able Pro–based web application already handles driver records, but the current edit page lags behind our newer add page. I want to keep every pixel of the existing interface while improving functionality inside the same core-PHP (mysqli) codebase running on XAMPP.

Here’s the precise work I need completed within the current project structure:

• Extend the driver edit form by adding the extra fields we will finalise together, then map them to the existing MySQL tables.
• Upgrade validations so they mirror the rules already used on the add form. Both client- and server-side checks are welcome as long as the experience remains seamless.
• Introduce update tracking: add updated_by and updated_on columns, populate them on every edit, and surface the “Last updated by/on” line visibly in the page footer.
• Tweak the page layout only as much as needed to fit the new fields—no redesign, no framework migration, no Able Pro modifications beyond what’s strictly required.
• Double-check every change to be sure nothing breaks the current UI or any other module.

All development must stay in raw PHP, using mysqli and the existing Bootstrap markup; JavaScript should respect the template’s components. Once complete, I’ll verify that the form saves correctly, validation fires as expected, timestamps and usernames appear, and every device view remains intact.
