fix: differentiate cache label from cache size label in TaskHeader

- Added new translation key "cacheSize" for cache size display
- Updated TaskHeader.tsx to use "cacheSize" key for byte size display
- Kept original "cache" key for token metrics display
- Updated all language translation files with appropriate translations

This resolves the UI confusion where two different metrics both showed "Cache" as their label.
