WEST COAST PEST /PEST LOGIN HOTFIX V2

Problem fixed:
- The previous /pest/api/login.php file had a PHP parse error.
- That parse error caused the login POST to return HTTP 500.

Overwrite this file:
- /public_html/pest/api/login.php

After overwrite:
1. Hard refresh https://uent.co.za/pest/attendance/
2. Try login again

If login still fails, the endpoint should now return a useful JSON message instead of a blind 500.
