refactor: standardize using cookie as persist state (#187)

* refactor: standardize cookie handling and js-cookie dependency

- Create cookie utility functions (getCookie, setCookie, removeCookie)
- Replace js-cookie usage in layout-context, authStore, and authenticated-layout
- Remove js-cookie and @types/js-cookie dependencies
- Update prettier import order configuration
- Maintain consistent cookie pattern across codebase

* refactor: update context providers to use cookie-based storage

- Replace localStorage with cookie handling for direction, font, and theme contexts.
- Introduce utility functions for cookie management (getCookie, setCookie, removeCookie).
- Ensure consistent cookie usage across all context providers for improved state persistence.

* refactor: simplify layout and search context providers
