feat(i18n): replace all hardcoded strings with translation calls

- Add translation keys for dashboard, send, receive, history, swap,
  pools, staking, lpStaking, fees, tokens, errors, validation, time,
  and context sections to types.ts and all 6 language files
- Replace hardcoded Kurdish/Turkish strings in all wallet components
  with useTranslation() hook t() calls
- Replace hardcoded strings in non-React files (crypto, utils,
  error-tracking, wallet-storage, contexts) with standalone translate()
- Fix Turkish strings incorrectly used in Kurdish codebase
