Get market price changes since a given ID

Returns market line price changes (new, updated, closed) since the specified last_id. Use for efficient polling.

Bootstrap flow: To obtain an initial last_id cursor, call GET /api/v2/sports/{sportID}/events/{date} — the response meta.delta_last_id provides the current cursor. Then pass that value as last_id to begin polling this endpoint.

Staleness guard: Cursors older than 30 minutes are rejected with HTTP 400. If your cursor becomes stale, re-bootstrap from the events endpoint.
