test: close ≥90% per-file coverage gaps for mid-session auth

The mid-session auth work passed `validate`/CI but failed the local-only
`npm run test:coverage` per-file gate (≥90% lines/statements/functions/
branches) on 12 files. Add targeted unit/integration tests so every changed
file clears the gate; annotate provably-dead defensive branches with justified
`/* v8 ignore */` comments rather than relaxing the gate.

Files brought to ≥90 on all four dimensions:
- core/auth: mcpAuth, oauthUx, utils, challenge, node/runner-interactive-oauth
- core/mcp: oauthManager, inspectorClient, node/authChallengeFetch,
  remote/remoteClientTransport, remote/node/{remote-session,server}
- clients/web/src/utils: oauthResume, browserTabVisibility

`npm run test:coverage` now passes (3575 tests, 0 threshold failures);
`npm run validate` green across all four clients.
