Add security hardening, captcha login, and password reset via email

- .htaccess: HTTPS enforcement, security headers, block sensitive files
- data/.htaccess: deny all direct access to data directory
- Secure session settings (httponly, secure, strict mode, samesite)
- Rate limiting on login (10 attempts per 15 min per IP)
- Math captcha on login form (server-side validated)
- Password reset via email with token (1 hour expiry)
- Forgot password UI with reset link flow
- Email field added to user management
- Updated .gitignore for reset_tokens.json and login_attempts.json
