Fixes we-promise#1809. SnaptradeAccount#upsert_balances! picked a single cash entry (account currency -> USD -> first) and stored only that in cash_balance; every other currency's cash was discarded. A moomoo Canada account with CAD $500 + USD $1000 imported only the CAD. Persist the full balances snapshot (new raw_balances_payload column) and surface each non-primary-currency cash entry as a synthetic per-currency cash holding (Security.cash_for(account, currency:)), mirroring the existing cash-security pattern. The primary currency stays in cash_balance. HoldingsProcessor now also runs for cash-only balances, and the Processor invokes it when there are holdings OR non-primary cash. Cash holdings use a stable external_id so repeated syncs update rather than duplicate.
