Mikael cc20e2c19c Fix foreign currency accounts using wrong exchange rate in balance sheet totals (#1010) ...

Balance sheet totals and accountable type summaries used a SQL JOIN on
exchange_rates matching only today's date, which returned NULL (defaulting
to 1:1) when no rate existed for that exact date. This caused foreign
currency accounts to show incorrect totals.

Changes:
- Refactor BalanceSheet::AccountTotals to batch-fetch exchange rates via
  ExchangeRate.rates_for, with provider fallback, instead of a SQL join
- Refactor Accountable.balance_money to use the same batch approach
- Add ExchangeRate.rates_for helper for deduplicated rate lookups
- Fix net worth chart query to fall back to the nearest future rate when
  no historical rate exists for a given date
- Add composite index on accounts (family_id, status, accountable_type)
- Reuse nearest cached exchange rate within a 5-day lookback window
  before calling the provider, preventing redundant API calls on
  weekends and holidays when providers return prior-day rates
