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.

Adds a Playwright spec that drives the dashboard end-to-end — opens
the chart overlay-controls popover, toggles target-range on, and
verifies the PUT /api/dashboard/chart-overlay-prefs round-trip fires.
Adds a vitest SSR test that pins the medication-compliance chart's
prefs-gated rendering: with the trend toggle off the 7-day trend chip
stays hidden; flipping it on paints the chip in the header. Mocks the
useChartOverlayPrefs hook so each test can dial the persisted state
directly without round-tripping the layout API.
