Andrei fb92160322 fix: Resolve black pages issue - Add missing auth slice and update checker ...

Fixed critical issues causing tracking pages to display black:
1. PWA service worker caching old JavaScript chunks
2. Missing auth Redux slice causing undefined errors

## Service Worker Update Checker
- Added /public/check-updates.js script
- Checks for SW updates every 60 seconds
- Auto-reloads page when new SW is activated
- Forces update check on page load
- Prevents future cache staleness issues

## Auth Redux Slice
- Created store/slices/authSlice.ts with User interface
- Added auth reducer to Redux store configuration
- Included auth in persist whitelist
- Provides selectors: selectUser, selectFamilyId, etc.
- Fixes "Cannot read properties of undefined (reading 'user')" error

## Root Cause
Tracking pages reference state.auth.user.familyId but auth slice
didn't exist in Redux store, causing TypeError on all tracking pages.
