Fix fingerprint login glitch

[SankethBK]

Fingerprint login works, but when app is opened fingerprint login prompt appears, disappears and then appears again. Ideally it should not disappear. Refer to this screen recording at 0:07

bug.webm

Fingerprint login is initiated in AuthPage widget located at lib/features/auth/presentation/pages/auth_page.dart.

This is the line of code starting the fingerprint login

widget.fingerPrintAuthRepository.startFingerPrintAuthIfNeeded();

Somehow entire AuthPage widget is getting re-rendered, logs might help to debug.
