fix: resolve all linting errors and type issues

- Remove unused setShowOfflineIndicator calls
- Remove unused areAllRelaysLocal import
- Fix duplicate key 'failedRelays' in console.log
- Replace 'any' types with proper HighlightEvent interface
- Add eslint-disable comments for intentionally excluded useEffect dependencies
- All linting errors resolved, type checks pass
