Linear accrual

[annamehr]

NAV management prefillment from data gathered from the runtime API

Spec linear accrueing in NAV dashboard

Already briefed Tim on prefill of asset prices.

UI can get prices when calling runtime API LoansAPI:Portfolio
Presentvalue needs to be taken and prefilled in the price fields

api.call.loansApi.portfolio(PoolId) -> Vec<(LoanId, LoanInfo)>

struct LoanInfo {
/// Related active loan
	pub active_loan: ActiveLoan<T>,

	/// Present value of the loan
	pub present_value: T::Balance,

	/// Current outstanding principal of this loan
	pub outstanding_principal: T::Balance,

	/// Current outstanding interest of this loan
	pub outstanding_interest: T::Balance,

	/// Current price for external loans
	/// - If oracle set, then the price is the one coming from the oracle,
	/// - If not set, then the price is a linear accrual using the latest
	///   settlement price.
	/// See [`ExternalActivePricing::current_price()`]
	pub current_price: Option<T::Balance>,
}
}
