Persist cookie settings across sessions

Restore cookie configuration on startup when previously active and the user opted to remember them. If config indicates a file source and the path exists, set cookie_file_path; if browser source, set browser_cookies_option. Treat missing "cookie_remember" as true by default. If the user did not opt to remember cookies, reset cookie_active to false. Added logging for restored settings and initialization state.
