Pre-existing format drift accumulated across v1.4.x; running
prettier brings the whole tree back to baseline so future diffs
read clean. No behaviour change.

Hook the overlay-controls dropdown into a TanStack Query mutation so
each chart's three toggle states (7-day trend / Trend arrow / Target
range) save per user and survive reloads. The prefs piggy-back on the
existing User.dashboardWidgetsJson blob with a `chartOverlayPrefs`
keyed by chart id, mirroring the v1.4.16 phase B8 comparison-baseline
pattern — no Prisma migration needed.
Wires up:
- GET /api/dashboard/widgets surfaces the resolved prefs in its
response so a fresh dashboard load knows which overlays to paint.
- PUT /api/dashboard/chart-overlay-prefs replaces a single chart's
prefs without round-tripping the whole layout.
- Existing PUT /api/dashboard/widgets preserves any chartOverlayPrefs
the client doesn't send, so saving widget visibility doesn't wipe
chart prefs.
- useChartOverlayPrefs hook reads + optimistically updates the cache.
- HealthChart, MoodChart, MedicationComplianceChart all consume the
hook, render the controls dropdown next to the range tabs, and gate
their three overlays behind the persisted toggles.
Default state for every chart, every flag: false. The clean line is
the new default; users opt into overlays they care about per chart.
