Refactor controllers and update envelope status handling

- Updated `TestEnvelopeHistoryController` to use `EnvelopeStatus` for status parameters and marked it as obsolete.
- Modified `TestViewController` with new route attributes, simplified constructor, and improved error handling in HTTP methods.
- Cleaned up `DebugEnvelopes.cshtml` by removing unnecessary using directives and ensuring type safety in envelope grouping.
