What is the current behavior?

HttpErrorByCode map in packages/common/utils/http-error-by-code.util.ts is missing MisdirectedException (421) and HttpVersionNotSupportedException (505). Both classes exist on disk and are exported from packages/common/exceptions/index.ts, but are absent from the ErrorHttpStatusCode type union and the HttpErrorByCode Record. Using errorHttpStatusCode: HttpStatus.MISDIRECTED in pipe options causes a TypeScript type error, and HttpErrorByCode[HttpStatus.MISDIRECTED] returns undefined at runtime.

Issue Number: N/A

What is the new behavior?

Both MisdirectedException and HttpVersionNotSupportedException are now imported, added to the ErrorHttpStatusCode type union, and mapped in the HttpErrorByCode Record — consistent with the 19 other exception classes already present. Added 5 unit tests verifying all 21 entries resolve to valid HttpException subclasses with correct status codes.
