feat(reports): admin Reports dashboard — ledger-first charts

Adds an admin Reports screen (/setup/reports, gated report:read) — an
on-demand dashboard over the signed event log.

Server (ledger-first): GET /api/reports/summary?from&to&bucket aggregates
in one call — entry/exit counts + all money summed straight from
ledger_events (same source the shift Z-report reconciles, so totals tie
out to the drawer); revenue split into ticket / subscription-sale /
out-of-window mirrors the Z-report. Duration stats come from the sessions
cache (flagged). All bucketing is in the SITE timezone (siteTz). A .csv
export of the per-bucket series. reports.ts + routes/reports.ts.

Web: Reports.tsx — date-range presets (today/7d/30d/90d), hour/day/month
grain, KPI cards, entry/exit line, revenue bar + cash/card split,
revenue-mix pie, peak-hours histogram, numeric breakdown, subscription
stats. Charts via Recharts (MIT), lazy-loaded into its own chunk
(~111KB gz) so the booth bundle is untouched. New Setup tab + nav + i18n
(sq + en parity). asc() exported from @parking/db; formatMinutes helper.

Tests: reports.test.ts (10) pin the sums, tz bucketing, money split,
duration stats, subscription counts. server 90/90; build+lint 14/14.

Wiki: reporting-analytics.md "Built v1" section + log entry.
