refactor: update Makefile commands for improved readability and effic…

…iency (#3596)

* chore(Makefile): redirect output of 'poetry install' and 'npm install' commands to /dev/null to reduce noise
chore(Makefile): redirect output of 'npm run build' command to /dev/null to improve build process efficiency
feat(Makefile): update build_frontend target to include copying built files to backend directory for deployment

* chore(Makefile): refactor lint target to depend on install_backend task for better dependency management
chore(Makefile): refactor frontend, frontendc, backend, build_and_run, build_and_install, and build targets to depend on setup_env task for consistent environment setup before execution

* chore(Makefile): update Makefile commands to use @ symbol for silent execution and improve readability

* chore(Makefile): update Makefile commands to use "@" to suppress command output and improve readability

* chore(Makefile): update run_cli target to include dependencies installation and frontend build steps for better clarity and consistency

* chore(Makefile): add command to delete empty directories in clean_python_cache target
