Staff public full width fix
===========================

Updated /hrms/staff_register.php and /hrms/staff_profile_update.php public wrapper via hrms_staff_profile_public_header().

Fixes:
- Removed Sneat layout-wrapper/container-xxl reserved left spacing from public staff pages.
- Public pages now render in 100% width using employee-public-page and employee-public-container.
- Kept Employee Profile / Registration design, accordions, icons and Add row JS intact.
