feat: Complete i18n localization for token statistics

Fix i18n violations by adding complete translations for token statistics tooltip.

Changes include:

- Add tokenStats section with inputLabel, outputLabel, and cacheLabel to all 18 language files

- Replace hardcoded strings in ChatRow.tsx with i18n calls

- Update formatTokens.ts to accept localized cache label parameter

- Translate shareSuccessPublic message to all supported languages

- Ensure proper localization for token usage display in API request tooltips

This resolves the automated code review rule violation (irule_C0ez7Rji6ANcGkkX)

and provides complete localization support for the token statistics feature.
