@Bafyn This fix is a rather big retfactor...

Pull request overview

This PR fixes and refactors form-url-encoded body matching by moving form/query parameter values from single strings to WireMockList<string> (to support multi-value keys) and by reworking matcher scoring logic accordingly.

Changes:

• Refactor form-url-encoded parsing and models to represent multiple values per key via WireMockList<string>.
• Rework FormUrlEncodedMatcher and parameter matching score calculations to better handle multi-value matching scenarios.
• Update/extend unit tests to cover single vs multiple values and AND/OR operator behaviors.
