Agents analytics roll-up

Signal-agent (watcher) performance for the token owner's team, proxied from the agents service: totals (agents, active agents, prospects found split into people and companies), a breakdown by agent kind and list type, a breakdown by agent status (active, paused, initializing, expired, ...) and the zero-filled prospects-found series (daily buckets for 7d, ISO-week buckets for 30d and 90d; each point's date is its bucket's start date as a display label ('Jan 1') with the same date as YYYY-MM-DD in isoDate). Only agents created inside the window are counted, together with the prospects those agents delivered. byType[].monitorType is the engine's own agent slug and is coarser than the type used to create agents: several slugs map to one public type. Rate limit: 20 requests per minute, 1000 per day.

Errors:

• 422 VALIDATION_FAILED — range was sent and is not one of 7d, 30d or 90d.
• 429 RATE_LIMITED — Per-user quota for this endpoint family exceeded (20 per minute, 1000 per day); retry after the Retry-After / RateLimit-Reset seconds.
