The CI coverage job failed with `ReferenceError: sessionStorage is not defined`.
`revocation-e2e.test.ts` used `BrowserOAuthStorage`, but the `integration`
vitest project runs in the node environment, not happy-dom. Node 22 gates Web
Storage behind a flag while newer Node exposes it by default, so it passed
locally and failed in CI. It uses `NodeOAuthStorage` with a temp dir now,
matching the other OAuth integration tests, with a comment naming the trap.
Also from Copilot review round 21: `listIssuers` and `getIssuerTokens` became
dead production API when `takeRevocationSnapshot` took over — a grep finds them
only in their own implementations and tests. Keeping them would widen the
exported `OAuthStorage` contract and force every implementation and mock to
carry methods nothing calls. Removed, along with their tests and the mock
entries in four suites.
