refactor: update API response handling across multiple queries to ensure compliance with ADR-028

- Removed direct return of json.data in favor of structured error handling.
- Implemented checks for success and data array in useActivityLogQuery, useBestSalePricesQuery, useBrandsQuery, useCategoriesQuery, useFlyerItemsForFlyersQuery, useFlyerItemsQuery, useFlyersQuery, useLeaderboardQuery, useMasterItemsQuery, usePriceHistoryQuery, useShoppingListsQuery, useSuggestedCorrectionsQuery, and useWatchedItemsQuery.
- Updated unit tests to reflect changes in expected behavior when API response does not conform to the expected structure.
- Updated package.json to use the latest version of @sentry/vite-plugin.
- Adjusted vite.config.ts for local development SSL configuration.
- Added self-signed SSL certificate and key for local development.
