feat(desktop-wallet): add smart contracts and tokens UI

Add complete frontend and backend implementation for smart contracts
and tokens management:

Backend (Rust/Tauri):
- Add contract_deploy, contract_call, contract_read, contract_get_info commands
- Add token_create, token_transfer, token_get_info, token_get_balance commands
- Add token_list_balances, token_mint, token_burn commands
- Add new error variants for validation and contract errors

Frontend (React/TypeScript):
- Add contracts Zustand store with persistence
- Add tokens Zustand store with persistence
- Add ContractsDashboard page with deploy/interact tabs
- Add TokensDashboard page with balances/create/transfer/manage tabs
- Update navigation sidebar with Contracts and Tokens links
- Add routes for new pages
