Performance

Get the brand's connected accounts with followers, following, followersGained over the last `days` days (7-365, default 30; net followers, gains minus losses, measured from the last snapshot at or before the start of the window, or from the first snapshot when the account was connected more recently) with followersGainedDays echoing the window, totalVideos, reach, source (oauth | scrape), lastSnapshotAt, lastSyncedAt, lastScrapedAt and lastUpdatedAt (source-aware sync/scrape freshness). Accounts without snapshots are always included in accountsWithoutSnapshots, even without includeHealth, and are still connected. includeHealth=true adds health per account: syncStale (no sync in the last 26h), tokenExpired (Instagram login expired, the account must be reconnected), firstSnapshotAt, missingSnapshotDaysLast30 (UTC days of the last 30 without a follower snapshot, counted from the first snapshot); includeHealth also adds health to accountsWithoutSnapshots. Does not return a day-by-day follower curve.
