Force password login flow when OTP redirect occurs

[FJabilee]

This PR introduces a "force password login" flow to handle cases where the site redirects users to the OTP (password-free) login page.

Changes included in this PR

• Added force_sign_in_url_password():

  • Detects if the driver is on an OTP redirect URL matching /secure/{courseID}/identity/login/otp.
  • Attempts to click the “log in with a password” link if it exists (id="login-with-password-link").
  • If the link is not found, constructs the equivalent password login URL /secure/{courseID}/identity/login/password?force=true and navigates to it.

• Updated find_login() to call force_sign_in_url_password() after navigating to the fallback /sign_in URL if the standard “Login” link is not found.

• Added logging around OTP detection and fallback URL navigation for better visibility.
