Move the bannerStateForResults helper into the SignaturePropertiesManager class (PR 21247 follow-up)

Browse Source 
This has a couple of advantages:
 - It allows accessing and iterating `this.#results` directly, without having to (needlessly) create a temporary array.

 - By moving the "worst status" computation into its own getter, it can be re-used from the `#updateButtonState` method as well which reduces code duplication.
