* Inline subtlecrypto shim The presence of this thing just makes code more confusing. * Remove pre-node-20 webcrypto hack Until node 20.0, the webcrypto API lived at `crypto.webCrypto`. It's now available at the same place as in web -- `globalThis.crypto`. See: https://nodejs.org/docs/latest-v20.x/api/webcrypto.html#web-crypto-api * oidc auth test: Clean up mocking THe previous reset code wasn't really resetting the right thing. Let's just re-init `window.crypto` on each test. * Remove `crypto` shim This isn't very useful any more.
