TypedParam should use validator configured in tsconfig just like TypedQuery / TypedBody

Summary

• nestia: 3.2.1
• typia: 6.0.6
• Expected behavior: I would expect TypedParam error to follow the same interface as TypedQuery and TypedBody.
• Actual behavior: TypedParam uses assert regardless of value in tsconfig

tsconfig:

{ 
    "transform": "@nestia/core/lib/transform",
    "validate": "validate"
}

Code:

@core.TypedRoute.Get(":id")
public test(
  @core.TypedParam("id") id: number,
  @core.TypedQuery() query: { x: number },
): void {}

TypedParam error (bug):

{
  "path": "$input",
  "reason": "Error on typia.http.parameter(): invalid type on $input, expect to be number",
  "expected": "number",
  "value": "d",
  "message": "Invalid URL parameter value on \"id\"."
}

TypedParam error (expected):

{
  "errors": [
    {
      "path": "$input",
      "expected": "number",
      "value": "d"
    }
  ],
  "message": "Invalid URL parameter value on \"id\"."
}

This change would unify their interfaces and make it easier to consume apis created with nestia.

As @TypedParam() decorated parameter has only one atomic type, I just used assert function only.

If you want the IValidation typed error message format, it is not hard thing, but have to connsider about when configured the validation function to be is() case. How it would be? Also, as it is a break change on the API level, if accept your suggestion, it would adapted in the next major version.

Thanks for quick response.

When is() is used, both TypedQuery and TypedBody return:

interface _ {
  message: string;
  error: "Bad Request";
  statusCode: 400;
}

I think TypedParam should follow that interface too.

Your opinion is correct. I'll update it as you want.
