search.suspended_time settings: bug fixes

* fix type in settings.yml: replace suspend_times by suspended_times
* always use delay defined in settings.yml:
  * HTTP status 402 and 403: read the value from settings.yml instead of using the hardcoded value of 1 day.
  * startpage engine: CAPTCHA suspend the engine for one day instead of one week
