Introduce centralized storage utilities to address SSR issues with direct
localStorage access in zustand slices and components. This adds ESLint
rules to prevent future regressions while preserving existing usages
via bulk suppressions.
- Add config/storage-keys.ts for centralized storage key definitions
- Add utils/storage.ts with SSR-safe get/set/remove operations
- Add workflow/store/persist-config.ts for zustand storage adapter
- Add no-restricted-globals and no-restricted-properties ESLint rules
- Migrate workflow slices and related components to use new utilities
