Refactor EmailTemplateDto and update command handler

The `EmailTemplateDto` class has been changed from a record with positional parameters to a class with explicit properties, including XML documentation and required modifiers for `Name`, `Body`, and `Subject`.

In the `ResetEnvelopeTemplateCommandHandler`, added necessary using directives, modified the constructor to accept an `IRepository<EmailTemplate>`, and updated the `Handle` method to read and update email templates based on the request's ID or type. The static `Default` collection has been renamed to `Defaults` and now uses `EmailTemplateDto`.
