This PR is a bit too big to review. We can merge it and I will test the features.
Switch from @demox-labs/miden-sdk v0.12 to @miden-sdk/miden-sdk v0.13. Add @openzeppelin/miden-multisig-client, psm-client, Para wallet SDKs, and @tanstack/react-query. Add PSM config, WASM copy paths, and Para module stubs in next.config.mjs.
Port initClient, multisigApi, helpers, errors, and procedures from the PSM example app. Add wallet type definitions (WalletSource, ExternalWalletState), PSM type definitions (SignerInfo), and hooks for Para wallet session and Miden Wallet adapter integration.
Create MultisigContext as the central state manager replacing the coordinator API layer. Manages WebClient, MultisigClient, signer keys, proposals, wallet source selection, and all PSM operations. Update Providers with ParaProvider, QueryClientProvider, and MultisigProvider tree.
Replace coordinator REST API calls with MultisigClient SDK operations across all dashboard pages, login flows, and transaction interactions. Use proposals from context instead of coordinator transactions. Switch account ID format from bech32 to hex.
Delete coordinator services (walletApi, transactionApi, signatureApi), old contexts (MidenClientContext), old hooks (useMidenSdk, useWalletData, useFungibleAssets), unused components (ConnectWalletModal, WalletInfo, DynamicWalletButton, etc.), and old type files. Simplify Redux store to only wallet form slice. Remove transactionSlice, signatureSlice, and walletStatsSlice.
Add AppHeader component showing wallet source selector, signer keys popover, and PSM endpoint status/editor. Rendered globally via Providers so it appears on login and dashboard pages. Auto-switches wallet source when Para or Miden Wallet connects.
- Signer 1 is now read-only and shows the active wallet's commitment - Other signers (2+) are added manually via commitment input - Persist account ID in cookie after create/load for middleware auth - Review step highlights Signer 1 with wallet source label
Return null from Providers before mount instead of rendering children without MultisigProvider, which caused a runtime error when dashboard components called useMultisig() during initial hydration.
- Auto-load account from localStorage after client initialization so dashboard shows correct signers/threshold on refresh - Call syncAll() after account creation to populate detectedConfig
Persist local Falcon/ECDSA keys in a separate IndexedDB (MultisigSignerKeys) so they survive page reloads without being cleared by clearMidenDatabase(). Normalize all signer commitments to 0x-prefixed lowercase hex to match the format the PSM server derives during signature verification, preventing 401 rejections from format mismatches.

Summary
Migrates the coordinator frontend from the coordinator REST API layer to the PSM (Private State Manager) SDK, replacing all server-mediated multisig operations with direct client-side interactions via @openzeppelin/miden-multisig-client.
