Let aggregate money figures use the install's currency

[puneet1409]

Running this on an INR portal, the overview shows two different currencies for
the same money: the open-deals list renders each row in the deal's own
currency, and the "Open pipeline" tile directly above it renders the total as
US$. Same page, same deals.

Every per-deal call site passes deal.currency. The aggregates — the tiles,
the stage donut, the chart tooltips, the deals-table footer — have no single
deal to read one from, so they fall through to the hard-coded "usd" default
in packages/ui/src/lib/format.ts. It's invisible on a USD install, which is
presumably why it's lasted.

This adds DEFAULT_CURRENCY, published to the bundle the same way
next.config.ts already publishes API_URL — a value that only exists in the
root .env is undefined in a client bundle, so the env map is the
mechanism that already works here. Unset, nothing changes.

Not multi-currency (#19) — a single-tenant CRM has one reporting currency, and
this is just making that one value not be a constant. Mixed-currency portals
would still need real conversion.

Biome passes. I couldn't run check-types locally: nestjs-trpc ships no
aarch64-pc-windows-msvc binary, so the generate step can't run on this
machine.

Summary by cubic

Aggregate money figures now use the install’s currency via DEFAULT_CURRENCY, fixing mixed USD/non-USD displays on overview tiles, stage donut, and table footers.

• Bug Fixes

  • Updated formatMoney and formatMoneyCompact in packages/ui/src/lib/format.ts to default to NEXT_PUBLIC_DEFAULT_CURRENCY instead of hard-coded "usd".
  • apps/app/next.config.ts publishes DEFAULT_CURRENCY as NEXT_PUBLIC_DEFAULT_CURRENCY; added docs in .env.example.

• Migration

  • Set DEFAULT_CURRENCY="inr" (or your install currency) in .env. If unset, behavior stays "usd".

Obsolete — I'd branched from a stale fetch. #39's reportingCurrency plus the multi_currency migrations already solve this properly, and sales-dashboard.tsx:60 now passes it through. Converting at a real rate beats a build-time constant. Sorry for the noise.
