fix(e2e): pause-resume mock used item, real contract is resource (#93)

The pause-resume.spec.ts route mock returned `{ok, item}`, but the agent
API's POST /resources/:id/pause|resume responds `{ok, id, token, status,
message, resource}` and api.pauseResource() reads `r.resource`. With the
wrong key adaptResource(undefined) threw, confirm()'s catch fired, and the
modal never closed — failing "Pause → confirm → Resume label flips" on
every run (incl. both retries). Mock now returns `resource`, matching the
backend handler (resource.go Pause/Resume) and api/index.ts.

Full chromium suite: 23 passed.
