Purpose

This pull request primarily focuses on cleaning up unused code and simplifying imports across multiple files. The main changes involve removing unnecessary imports, unused hooks, and redundant code, which helps improve maintainability and clarity.

Code cleanup and simplification:

• Removed unused imports such as PayloadAction, makeStyles, useCallback, and useState from various files including Redux slices and component files. [1] [2] [3] [4] [5] [6]
• Eliminated unused hooks and variables like useHeaderHooks, useFluent, and related destructured values in components, streamlining the code. [1] [2] [3] [4]
• Removed unused imports and code from authentication-related files, including msalInstance, loginRequest, and useMsal.
• Cleaned up error handling in httpUtility.ts by removing the unused isNetworkError variable.
• Deleted unused imports such as toast and updatePanelCollapse from panel and slice files. [1] [2]
