The health/deep checks handler inlined its own base64url cursor encode/decode and page-slicing logic. Extracted it into a generic paginateByCursor() in src/cursorPagination.ts (mirroring the offset pagination helper already shared between the api-keys and webhooks list endpoints) and refactored the health handler to use it. No behavior change; this is the shared entry point subsequent metrics pagination work will build on.
/api/v1/metrics and /api/v1/stats now reject any query parameter with a structured 400 invalid_request; neither route accepts parameters today.
Adds servicesBreakdown (per-service tenantId/serviceId/priceStroops/ requestsOutstanding) to GET /api/v1/stats, cursor-paginated via the shared paginateByCursor() helper (limit default 50, max 500, stable nextServicesBreakdownCursor). /api/v1/metrics itself stays unpaginated Prometheus exposition text, since paginating a scrape target would break standard Prometheus clients.

nextServicesBreakdownCursor). A malformedor expired cursor returns
400 invalid_request./api/v1/metricsitself stays unpaginated Prometheus exposition text —paginating a scrape target would break standard Prometheus clients, so

Note
Stacked on #415 and #416 (same fork-only caveat noted on other PRs in
this series). The pagination-specific change is the

src/routes/metrics.ts.
