Refactor hooks and contexts for improved state management and modularity

- Updated `useActiveDeals` hook to include reset functionality for API calls.
- Enhanced `useApi` hook to provide a reset method for clearing state.
- Refactored `useAuth`, `useFlyers`, `useMasterItems`, `useModal`, and `useUserData` hooks to utilize context providers for better state management.
- Created new context files: `AuthContext`, `FlyersContext`, `MasterItemsContext`, `ModalContext`, and `UserDataContext` to encapsulate related state and logic.
- Updated tests for hooks to accommodate changes in context structure and reset functionality.
- Adjusted imports in `index.tsx` to reflect new context structure.
