The Overdue Command Center and Price-Change (drift) panels reset to
expanded on every load — their collapse arrows used local useState. Now
the collapsed state is remembered per-user via two new settings
(tracker_overdue_collapsed / tracker_drift_collapsed), mirroring the
search panel's useSearchPanelPreference pattern. Each panel header also
gains an inline "Hide" control (EyeOff, like the search panel) that writes
the existing tracker_show_* setting and fires an Undo toast; hidden
sections come back from Settings → Tracker Layout.
- services/userSettings.js: allowlist + defaults for the two collapse keys
- TrackerPage: read collapse state, hide handlers with Undo, wire props
- OverdueCommandCenter/DriftInsightPanel: controlled collapse + header hide
Verified: typecheck 0, lint 0 errors, build, and a live settings round-trip
(collapse persists, hide writes, Undo restores, allowlist rejects junk keys).
