fix(ci): run api root lint/typecheck/test scripts; remove dead servicesTable (GRO-2197)

The api gate ran `pnpm --filter @groombook/api <script>`, but @groombook/api
is the workspace ROOT package and pnpm-workspace.yaml only includes packages/*,
so --filter excluded the root and the lint/typecheck/test steps silently
no-op'd (false-green). Invoke the root scripts directly instead.

Now that the gate actually runs eslint, fix the latent unused-var error in
src/__tests__/petProfileSummary.test.ts: servicesTable was declared and
assigned in resetMock but never enqueued/read. Remove the declaration, the
dead write, and the now-orphaned makeService helper (its only caller).

Verified locally: pnpm run typecheck, pnpm --filter @groombook/db typecheck,
pnpm run lint (0 errors), pnpm run test (602 passed) all green.
