Use Mongoose timestamps option to automatically handle createdAt and updatedAt fields

[katiyarkartik0]

In MongoDB with Mongoose, you do not need to manually create a createdAt field if you're using Mongoose's built-in timestamps option. This option automatically adds createdAt and updatedAt fields to your schema.

By setting the timestamps option to true in the schema, Mongoose will automatically handle the createdAt and updatedAt fields for you.

At backend/src/models/coreModels, backend/src/models/appModels/Client.js, backend/src/controllers/appControllers/clientController/summary.js, backend/src/models/appModels/Invoice.js, backend/src/models/appModels/Payment.js, backend/src/models/appModels/PaymentMode.js, backend/src/models/appModels/Quote.js, backend/src/models/appModels/Taxes.js, backend/src/models/coreModels/Admin.js , backend/src/models/coreModels/Upload.js we can see the explicit declaration of created field.

We shall use timestamp boolean instead.
