Description

Fix Project-wide ESLint Errors and Refactor Blog Data Structure

---

📌 Description

This PR resolves 27 linting errors and warnings identified across the project to improve code quality and build stability. It also includes a significant refactor of the Blog component to separate data from the UI, resolving "Fast Refresh" warnings.

Key Changes:

• Refactored Blog Structure: Moved generateBlogPosts and large image imports from components/Blog.jsx to a dedicated data/blogData.js file.
• Fixed Data File: Replaced incorrect component code in src/data/blogData.js with the actual data generation logic.
• Cleaned Code: Removed unused variables, imports (e.g., useTheme, setHoveredPlan), and unnecessary eslint-disable directives across multiple files (Navbar, Pricing, features, Login).
• Config Updates:
  • Updated eslint.config.js to permit unused variables named motion (common in Framer Motion).
  • Fixed vite.config.js to correctly define __dirname in an ES Module environment.
• Logic Fixes: Added missing dependency to useCallback in AuthContext and fixed catch block syntax in utility files.
