Build Backend for Stories Page: Implement CURD operation Routes ✨🚀

[Sawan-Kushwah]

issue : #1830

fixes : #1830

This PR implements the backend for the Stories page, including the following:
GET /api/posts: Fetches all the stories (posts) from the database.
POST /api/posts: Allows users to create and save new stories by submitting title, content, and category data.
The data is stored in a MongoDB database using Mongoose, and the backend handles both the creation and retrieval of posts.

Changes include:

Creation of routes and controllers for handling posts.
Integration of Mongoose for database interaction.
Validation to ensure necessary fields are provided before saving a new post.

This sets up the backend to support the stories functionality on the frontend.
