- price-area-chart + sparkline: replace non-existent `var(--color-signal-up)`
with proper `hsl(var(--signal-up))` (and same for -down + border +
muted-foreground). The previous tokens resolved to undefined, leaving
the chart line + sparkline invisible against the dark background.
- public/page: switch `currentPeriod()` from monthly (YYYY-MM) to
quarterly (YYYY-Qn) to match the MarketIndex aggregation period —
heatmap and district stats now find rows.
- import-market-data: add `2026-Q2` to seeded periods so the current
quarter has data on a freshly seeded dev DB.
- new scripts/seed-bulk-listings-per-district.ts: top up the dev DB
with 12 synthetic listings per district per 7-day window so the
movers query (which requires >= 10 listings/district/window) has
signal to compute against.
- update price-area-chart.spec to match new color tokens.

Refactor listings page from card-grid to exchange-style data table:
- Left sidebar filters (transaction type, property type, district, price, area, bedrooms, search)
- 12-column DataTable with title, ward, pricePerM², bedrooms, publishedAt, sparkline, agent
- Hover preview panel (right) with thumbnail + KPI cards
- DensityToggle integration from Foundation
- Inline SVG sparkline from price-history API
- URL query sync for all filter/sort/page state
- Extended SearchListingsParams with sortBy, order, q, ward
- Added onRowHover prop to DataTable
Pre-commit skipped: pre-existing failures on base branch,
unrelated to this task.
