Get daily aggregate ad metrics for an account

Returns daily aggregate metrics across all ads in a SocialAccount as a single time series — one row per calendar day in the requested range. Use this for dashboards that draw a daily-spend or daily-conversions chart, instead of calling `/v1/ads/tree` once per day. `accountId` is required. The lookup is sibling-expanded so passing the `metaads` ID also includes ads under the linked `facebook` / `instagram` posting account (and vice-versa) — same convention as `/v1/ads/tree` and `/v1/ads`. Date range defaults to the last 90 days. Capped at 730 days. Ranges older than the 90-day cache window trigger an on-demand backfill from the platform before returning.
