iEduPortal Stage 6 — One-Time Pupil1 Password Reset

Purpose:
Reset ONLY pupil ID 1 whose username is Pupil1 to the password Pupil1.
The password is stored using PHP password_hash().

Upload:
Extract this package into the existing public web root so that:
  upgrade/stage6reset/index.php
exists.

Open:
  /school-management-system/public/upgrade/stage6reset/index.php?token=IEDU-STAGE6-RESET-7Q4K9M2X

Click "Reset Pupil1 Password" once.

After a successful reset:
1. Remove the entire upgrade/stage6reset/ folder from the server.
2. Test pupil.php with:
   Username: Pupil1
   Password: Pupil1
3. Do NOT import SQL.

Safety:
- Only UPDATEs pupil id=1 AND user='Pupil1'.
- Uses a prepared statement.
- Does not display the existing password or hash.
- A local completion marker prevents a second reset from this utility.
