## Summary
- **Bug fix:** Dashboard and accounts index cards displayed the
account's original currency code (e.g. `BTC`) even though balances were
already converted to the user's currency (e.g. `EUR`). Now passes
`displayCurrencyCode` to card components so the label matches the
converted amount.
- **Feature:** Added a currency toggle on the account detail chart to
switch between the account's native currency and the user's main
currency. Extends the balance evolution APIs with `display_*` fields
when conversion applies.
- **First-account restriction:** Restricts first-account creation to
primary (fiat) currencies only, ensuring the user's base currency is
always widely supported.
## Changes
### Bug fix — currency label on cards
- `AccountBalanceCard` / `AccountListCard`: Added `displayCurrencyCode`
prop; all amount renders now use it instead of `account.currency_code`
- `dashboard.tsx`: Passes `netWorthEvolution.currency_code` as
`displayCurrencyCode`
- `Accounts/Index.tsx`: Passes `auth.user.currency_code` as
`displayCurrencyCode`
### Backend — API extension
- `DashboardAnalyticsController`: Both `accountBalanceEvolution()` and
`accountDailyBalanceEvolution()` now return `display_value`,
`display_invested_amount`, `display_mortgage_balance` per data point and
a top-level `display_currency_code` when the account currency differs
from the user's
### Frontend — currency toggle
- New `ChartCurrencyToggle` component with `ToggleGroup` showing
currency code labels (e.g. `BTC` / `EUR`)
- `ChartSettingsPopover`: Extended with optional `currencyToggle` prop
for mobile
- `AccountBalanceChart`: Full integration — all amounts, trends,
tooltips, MoM chart, and equity swap to `display_*` values when toggle
is set to user currency
### First-account currency restriction
- `StoreAccountRequest`: First account limited to primary currency codes
- `AccountForm` / `CreateAccountDialog` / `StepCreateAccount`: Pass
`usePrimaryCurrenciesOnly` when applicable
### Tests
- 5 new Pest tests for `display_*` fields in balance evolution endpoints
- 3 new Vitest tests for `deriveAccountMetrics` (mixed-currency, empty
data, invested amounts)
- 1 new Pest test for first-account BTC rejection
## Why
Investment and retirement accounts show balance over time, but there's
no way to see how much money was actually put in versus how much is
current value. Users can't tell at a glance whether their investments
are up or down.
## What
Adds an "invested amount" tracking system across the full stack:
**Backend**
- New `invested_amount` column on `account_balances` (nullable
bigInteger, cents, per-date)
- Auto-sync from providers: Indexa Capital (instruments_cost +
cash_amount), Bitpanda (fiat deposit/withdrawal history), Binance
(90-day windowed deposit/withdrawal with crypto→fiat conversion)
- Manual input support via Update Balance dialog
- Historical invested amount data in all balance evolution APIs (net
worth, account detail)
**Frontend**
- Dashed line on sparkline charts (dashboard + accounts page) showing
per-point historical invested amount alongside balance
- Dashed line on account detail charts (daily AreaChart + monthly
ComposedChart)
- Tooltips with labeled rows: Balance, Invested, Gain/loss (color-coded)
- Invested amount column in balances history modal
- Invested amount field in balance import wizard (CSV mapping)
- Demo account seeder updated with invested amount data

## Summary
- Add Bitpanda as a new exchange provider using a single API key
(`X-Api-Key` header) to sync crypto and fiat wallet balances
- Follow the same architecture as Binance: provider string on
`banking_connections`, dedicated API client, balance sync service,
controller, form request, job wiring, factory state, route, and frontend
dialog
- Convert crypto wallet balances to the user's target currency via
`CurrencyConversionService`; fiat wallets are added directly or
converted if in a different currency
- Bitpanda appears in all countries in the connect dialog (same as
Binance)
- 18 new tests covering controller validation, balance sync scenarios,
sync job delegation, expiry handling, and email suppression
