Fix CLI auth crash: pin @noble/curves v2 in CLI, add e2e tests to CI

The CLI's core-dist imports @noble/curves/secp256k1.js (with .js extension),
which requires v2's exports map. viem was pulling in v1.2.0 transitively into
cli/node_modules, which only exports ./secp256k1 (no .js) — causing
ERR_PACKAGE_PATH_NOT_EXPORTED on every authenticated command.

- Add @noble/curves and @noble/hashes ^2.0.1 as direct CLI dependencies
- Add e2e tests to npm test and CI workflow so this class of bug is caught
