West Coast Pest /pest logout fix

Overwrite these files into /public_html/

- pest/api/logout.php
- pest/attendance/app.js

Why this fix exists:
- The user was staying in the logged-in UI after tapping Logout.
- This patch makes logout "client-first": it always clears local/session storage immediately,
  then attempts server-side session cleanup as best effort.
- The backend logout endpoint now returns success even if server token cleanup fails,
  so the user is never trapped in the logged-in screen.

After upload:
1. Open https://uent.co.za/pest/attendance/
2. Hard refresh
3. Login
4. Tap Logout
5. You should return to the login screen immediately
