Add initial project structure with core functionality for book and stationery uploads
- Created main application entry point in `main.go`. - Added configuration management in `config/config.go` and tests in `config/config_test.go`. - Implemented handlers for book and stationery uploads in `handlers/book.go` and `handlers/stationery.go`, including validation logic. - Established database connection and services in `services/database.go` and `services/book_service.go`. - Defined models for books and stationery in `models/book.go` and `models/stationery.go`. - Set up Firebase integration for image uploads in `services/firebase.go`. - Created migration scripts for database schema in `migrations/001_create_tables.sql` and subsequent updates. - Added CORS and error handling middleware. - Included comprehensive tests for handlers, services, and utilities. - Documented API endpoints and usage in `README.md` and migration instructions in `migrations/README.md`. - Introduced `.gitignore` to exclude unnecessary files and directories. - Added Go module support with `go.mod` and `go.sum` files. - Implemented utility functions for slug generation and validation in `utils/slug.go` and `utils/validation.go`.
