Pull Request Overview

This PR introduces typed abstractions for MIME messages and parts, replacing untyped object usage with new IMimeMessageData and IMimePartData interfaces, and updates utilities, matchers, and tests to leverage these wrappers.

• Define IMimeMessageData, IMimePartData, IMimeEntityData, IContentTypeData, and IContentDispositionData interfaces.
• Implement wrapper classes (MimeMessageDataWrapper, MimePartDataWrapper, etc.) that adapt MimeKit types to the new interfaces.
• Refactor IMimeKitUtils, RequestMessage, RequestMessageMultiPartMatcher, and MimePartMatcher to use the new abstractions and remove legacy GetBodyParts.
• Update tests to use message.BodyParts instead of MimeKitUtils.GetBodyParts.

src/WireMock.Net.MimePart/Models/ContentDispositionDataWrapper.cs:37

• Returning object for Parameters may force consumers to cast. Consider exposing a more specific type (e.g., IReadOnlyDictionary<string, string> or IEnumerable<string>) to make the API easier to use and reduce the need for casting.

    public object Parameters => _contentDisposition.Parameters;

[Copilot]

Instead of calling ToString and replacing the header prefix, consider using the Disposition property on IContentDispositionData directly (e.g., mp.ContentDisposition?.Disposition) to match the value more explicitly.

Suggested change

	mp => ContentDispositionMatcher?.IsMatch(mp.ContentDisposition?.ToString()?.Replace("Content-Disposition: ", string.Empty)) ?? MatchScores.Perfect,
	mp => ContentDispositionMatcher?.IsMatch(mp.ContentDisposition?.Disposition) ?? MatchScores.Perfect,
