Add GraphQL queries for identity insights: current financials, unrealized P&L, realized returns, dividends

Add 4 new named queries used by the Wealthsimple insights page:

- FetchIdentityCurrentFinancials: time-range-aware net liquidation value,
  net deposits, and simple returns for an identity filtered by account IDs.
  Supports optional $startDate for computing returns over a specific period.

- FetchAccountUnrealizedPnL: unrealized P&L (amount + rate) for a specific
  account via account.financials.currentCombined.unrealizedPnL.

- FetchIdentityRealizedReturns: realized capital gains total value with
  per-security breakdown (symbol, name, total value), paginated.

- FetchDividendsV2: dividend income total with optional per-issuing-security
  breakdown (symbol, name, total value).
