HireFlow v1.2 does not implement CSRF token validation on any state-changing POST endpoint

HireFlow v1.2 does not implement CSRF token validation on any state-changing POST endpoint. All forms (password change at /profile, candidate deletion at /candidates/delete/<id>, feedback submission at /feedback/add/<id>, interview scheduling at /interviews/add) are vulnerable to CSRF. An attacker who can trick an authenticated user into visiting a malicious page can silently change the victim's password, delete records, or inject arbitrary data on their behalf. The SESSION_COOKIE_SAMESITE attribute is also not configured, removing the browser-level CSRF defense.
