Centralized common code into shared/ folder to eliminate duplication and
improve maintainability across all three frontend projects (web, mobile,
pezkuwi-sdk-ui).
Changes:
- Added token types and constants to shared/types/tokens.ts
- TokenInfo, PoolInfo, SwapQuote, and other DEX types
- KNOWN_TOKENS with HEZ, PEZ, wUSDT definitions
- Token logos (🟡🟣💵)

- Kesk, Sor, Zer, Spî, Reş color definitions
- Added TOKEN_DISPLAY_SYMBOLS mapping (USDT vs wUSDT)
- Updated blockchain configuration in shared/blockchain/polkadot.ts
- Added beta testnet endpoint (wss://beta-rpc.pezkuwi.art)
- Defined DEFAULT_ENDPOINT constant
- Moved i18n to shared/i18n/
- Centralized translation files for 6 languages (EN, TR, KMR, CKB, AR, FA)
- Added LANGUAGES configuration with RTL support
- Created isRTL() helper function
- Updated web and mobile to import from shared
- web/src/types/dex.ts now re-exports from shared
- web/src/contexts/PolkadotContext.tsx uses DEFAULT_ENDPOINT
- mobile/src/i18n/index.ts uses shared translations
- mobile/src/contexts/PolkadotContext.tsx uses DEFAULT_ENDPOINT
- Updated shared/README.md with comprehensive documentation
This architecture reduces code duplication and ensures consistency across
all frontend projects.
