🧩 fix: Redirect Stability and Build Chunking (#11965)

* 🔧 chore: Update Vite configuration to include additional package checks

- Enhanced the Vite configuration to recognize 'dnd-core' and 'flip-toolkit' alongside existing checks for 'react-dnd' and 'react-flip-toolkit' for improved handling of React interactions.
- Updated the markdown highlighting logic to also include 'lowlight' in addition to 'highlight.js' for better syntax highlighting support.

* 🔧 fix: Update AuthContextProvider to prevent infinite re-fire of useEffect

- Modified the dependency array of the useEffect hook in AuthContextProvider to an empty array, preventing unnecessary re-executions and potential infinite loops. Added an ESLint comment to clarify the decision regarding stable dependencies at mount.

* chore: import order
