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

* Fix linked account balance currency mismatch
When linking accounts from providers (Lunchflow, SimpleFIN, Enable Banking),
the initial sync was creating balances before the correct currency was known.
This caused:
1. Opening anchor entry created with default currency (USD/EUR)
2. First sync created balances with wrong currency
3. Later syncs created balances with correct currency
4. Both currency balances existed, charts showed wrong (zero) values
Changes:
- Add `skip_initial_sync` parameter to `Account.create_and_sync`
- Skip initial sync for linked accounts (provider sync handles it)
- Add currency filter to ChartSeriesBuilder query to only fetch
balances matching the account's current currency
* Add migration script and add tests
* Update schema.rb
