Closes WOOMOB-1305

Description

This PR addresses iOS17 deprecation warnings in account and authentication flows, as well as settings. We address two types:

• Usage of the one of the textView delegates
• UI updates on trait changes

Changes

• For trait changes, we just move to the new UITrait API
• For the textView delegate, we update it with the recommendation. Looking at the UIKit.UITextView interface we've lost URL as a parameter, and the return type is no longer Bool but optional UIAction?, so we have to return nil to prevent the default action.

   @available(iOS, introduced: 10.0, deprecated: 17.0, message: "Replaced by primaryActionForTextItem: and menuConfigurationForTextItem: for additional customization options.")
    optional func textView(_ textView: UITextView, shouldInteractWith URL: URL, in characterRange: NSRange, interaction: UITextItemInteraction) -> Bool 

...

    /**
     * Asks the delegate for the action to be performed when interacting with a text item. If a nil action is provided, the text view
     * will request a menu to be presented on primary action if possible.
     *
     * @param textView  The text view requesting the primary action.
     * @param textItem  The text item for performing said action.
     * @param defaultAction The default action for the text item. Return this to perform the default action.
     *
     * @return Return a UIAction to be performed when the text item is interacted with. Return @c nil to prevent the action from being performed.
     */
    @available(iOS 17.0, *)
    optional func textView(_ textView: UITextView, primaryActionFor textItem: UITextItem, defaultAction: UIAction) -> UIAction?

Test Steps

• Unlock the orientation lock in your device
• In the app, observe the main dashboard/tab bar responds normally when the device is set portrait/landscape
• Go to Menu > Settings > Tap Privacy, and the web link. Should work normally.
• Go to Menu > Settings > WooCommerce > Tap Work with us. Should work normally.
• For login cases I wasn't quite sure which flows to test, the affected files for the trait orientations are "role error", "account miss-match", and "error on Unified Login flow". I tried a couple of incorrect logins from the smoke test list and worked fine (ie: incorrect credentials, wrong account)
