Some Codex plans (e.g. Plus) return only a weekly window in `primary` with
`secondary: null`. applyCodexUsageToAccount dereferenced `secondary.usedPercent`
unconditionally, throwing a TypeError that refreshActiveCodexUsage swallowed at
debug level, so usage never applied and the dashboard row stayed blank (-1).
Guard the null secondary, and when a lone window is weekly (windowDurationMins
> 1440) route it into the 7d slot leaving 5h unknown. Accounts that report both
windows are unchanged. Adds a regression test for the secondary:null case.
Extract dashboard-usage-rows.ts (UsageRow, formatResetRemaining,
mergeClaudeDashboardAccounts, buildClaudeUsageRows, extractCodexUsageRows)
and codex-usage-collector.ts (fetchCodexUsage, applyCodexUsageToAccount,
buildCodexUsageRowsFromState, refresh functions returning data instead of
mutating module state). unified-dashboard.ts drops from 926 to 563 lines.
