chore(ci): bump API contract boundary audit route-count baseline to 884 (#5375)

The pinned totalRoutes/zodRoutes baseline (883) went stale after a
legitimate new Zod-contract-compliant route merged without the
required ratchet bump, breaking check:api-validation:strict on
staging HEAD itself. Actual count is 884 total / 884 zod / 0 non-zod
routes — a pure headcount update, no policy violation.
