fix: resolve 4 CI failures - pnpm setup, ESLint, jsdom, ethnum

1. pnpm setup: Moved pnpm/action-setup@v4 before actions/setup-node in all workflows
2. ESLint: Created packages/crypto/eslint.config.js with flat config format for ESLint 9
3. jsdom: Downgraded to 24 in apps/frontend to resolve ERR_REQUIRE_ESM
4. ethnum: Pinned to 1.4.0 in root Cargo.toml and updated Cargo.lock

All critical CI failures now resolved.
