Fix touch state not being activated in iOS Safari

This commit resolves the issue with the `:active` pseudo-class not
activating in mobile Safari on iOS devices. It introduces a workaround
specifically for mobile Safari on iOS/iPadOS to enable the `:active`
pseudo-class. This ensures a consistent and responsive user interface
in response to touch states on mobile Safari.

Other supporting changes:

- Introduce new test utility functions such as `createWindowEventSpies`
  and `formatAssertionMessage` to improve code reusability and
  maintainability.
- Improve browser detection:
  - Add detection for iPadOS and Windows 10 Mobile.
  - Add touch support detection to correctly determine iPadOS vs macOS.
  - Fix misidentification of some Windows 10 Mobile platforms as Windows
    Phone.
  - Improve test coverage and refactor tests.
