Remove unused fields from API Responses

[chavda-bhavik]

Is your feature request related to a problem? Please describe.
It seems obvious that the createdAt, updatedAt, and __v fields are not used anywhere on the front end. so we can remove them from API responses.

Describe the solution you'd like

1. Add an Exclude decorator to an entity, like,

import { Exclude } from 'class-transformer';
export class MyEntity {
  ...
  @Exclude()
  createdAt: Date;
  @Exclude()
  updatedAt: Date;
  @Exclude()
  __v?: number;
}

2. Add __v in the SchemaDocument,

interface IMyDocument extends MyEntity, Document {
  _id: never;
  __v: never;
}

4. In the controller apply the ClassSerializerInterceptor interceptor, like,

import { Body, ClassSerializerInterceptor, UseInterceptors } from '@nestjs/common';
...

@UseInterceptors(ClassSerializerInterceptor)
export class MyController {
  ...
}

5. Build dal lib by running pnpm build:dal.
6. Test respective API is sending the correct response.

3. ProjectEntity and ProjectController
