refactor(passport): replace ethers with viem in wallet package

[shineli1984]

Summary

Replace ether with viem in wallet package.

---

Note

Migrates the Wallet SDK from ethers to viem, introducing a WalletSigner/MessageSigner abstraction, refactors zkEVM/crypto flows and types to viem (bigint/Hex), updates Passport/x‑client crypto, and adds EIP‑712 typed‑data normalization with tests.

• Wallet SDK (viem migration & type cleanup)
  • Replace ethers with viem across wallet: introduce WalletSigner interface and use viem’s PublicClient, encodeFunctionData, hashMessage/hashTypedData, keccak256, toBytes.
  • Refactor zkEvm modules (walletHelpers, relayerClient, personalSign, sendDeployTransactionAndPersonalSign, signEjectionTransaction, zkEvmProvider) to use viem and getChainId; convert BigNumberish/hex types to bigint/Hex.
  • Add utils/crypto.signRaw (ethers-free) and utils/string using viem byte utilities.
  • Introduce WalletSigner and update magicTEESigner to implement it (no longer extends ethers Signer; returns typed 0x${string}).
  • Update types and zkEvm type defs (bigint values, EIP‑6963 types), adjust guardian client and sequence compatibility to viem enc/decoding.
• EIP‑712 & signing
  • New signTypedDataV4 with robust chainId normalization (transformTypedData) and added unit tests; packing/signing refactored to viem hashing; signERC191Message uses viem hashMessage.
• Passport SDK / Toolkit signer abstraction
  • Replace ethers.Signer with lightweight MessageSigner in starkEx flows and toolkit crypto.signRaw/generateIMXAuthorisationHeaders.
  • registerOffchain/registration now accept MessageSigner; getStarkSigner uses MessageSigner for legacy Stark key derivation.
• x-client updates
  • Add MessageSigner type; switch crypto helpers (signRaw, generateIMXAuthorisationHeaders, signMessage) and Stark key derivation to use it; minor minting import tweaks.
• Build/Deps
  • @imtbl/wallet: remove ethers, add viem; add tsup and adjust dev deps.
  • packages/game-bridge: bump parcel to ^2.13.3.
