Soumettre #829543: sayan365 student-management-system 1.0 Unauthenticated Access

The project enforces login checks only on `index.php`, `add_*`, and `view_*` pages. However, multiple critical **edit** and **delete** endpoints completely lack any session validation. Files like `edit_student.php` do not call `session_start()` and never check for `$_SESSION['username']`. As a result, an unauthenticated attacker can directly access these pages, read existing data, submit modifications, or trigger deletion actions without ever logging in.

Example from `edit_student.php`:
```php
<?php
include 'db.php';
if (isset($_GET['id'])) {
// no session check at all
...
if ($_SERVER['REQUEST_METHOD'] === 'POST') {
// update logic
}
}
```
