[WCiOS17] Notice presenter trait updates

[RafaelKayumov]

WOOMOB-1306

Description

Replaces old deprecated traitCollectionDidChange(_:) override with model API alternative to resolve warnings.

Testing steps

• Invoke any notice toast presentation. For example switch between stores in "Menu" -> Store selector.
• Wait until the "Switched to " toast is presented.
• While the toast is presented rotate the device to landscape mode and back.
• Make sure the toast is properly resized.

Testing information

Tested on iOS 26 iPhone 17 simulator.

• I have considered if this change warrants user-facing release notes and have added them to RELEASE-NOTES.txt if necessary.
