fix: support generic type in additional interfaces

[vbreuss]

This PR improves support for generic types in generated “additional interfaces” mock extensions and tightens up HTTP content/form-data matching behavior through updated tests and parsing.

Key Changes:

• Add coverage for matching when a parameter also implements IHttpRequestMessagePropertyParameter<HttpContent?>.
• Adjust multipart form-data extraction to preserve line endings/whitespace as read.
• Sanitize generated extension names to handle generic type names (angle brackets).
