**`resolver-validation.pipe.ts`**: Wrapped the `plainToInstance` call in a try-catch that converts any `@Transform` decorator errors into `UserInputError` GraphQL responses. Previously, if a `@Transform` function threw (e.g., `TypeError: options?.map is not a function`), the error propagated as an unhandled exception captured by Sentry. Now, these malformed-input errors are returned to the client as proper GraphQL `UserInputError` responses with a descriptive message, reducing Sentry noise from client-side input issues.
This follows the existing pattern in the same file where `safeClassValidatorValidateWrapper` already catches validation errors, and the pipe already throws `UserInputError` for invalid inputs.
