feat: add wallet UI with 4 tabs and HomePage summary

- chain.js: API wrapper with Idempotency-Key auto-generation
- WalletPage: 4-tab container (wallet/assets/inventory/market)
- WalletTab: balance, address (truncated+copy), key export
- AssetsTab: asset list with detail expand, market listing
- InventoryTab: read-only slot display
- MarketTab: buy/cancel with confirm dialog, all/mine filter
- WalletSummary: HomePage card with balance + stats
- PrivateRoute guard for /wallet, header link on HomePage
