feat: internationalize task metadata fallback names

- Add translation support to taskMetadata.ts using t() function
- Add 'incomplete' and 'no_messages' keys to all supported locales
- Replace hardcoded English strings with i18n keys:
  - 'Task #{{taskNumber}} (Incomplete)' → 'common:tasks.incomplete'
  - 'Task #{{taskNumber}} (No messages)' → 'common:tasks.no_messages'
- Translations added for all 16 supported languages:
  ca, de, en, es, fr, hi, it, ja, ko, nl, pl, pt-BR, ru, tr, vi, zh-CN, zh-TW
- Verified complete translation coverage with missing translations script
