* Allow SetAccountCurrency after SetCash without throwing
Previously, calling SetAccountCurrency after SetCash threw an
InvalidOperationException. The portfolio manager now switches the
base account currency in place: the previous Cash entry (and its
balance) is preserved in the CashBook, and a notice is logged. When
the new account currency matches the existing one, an optional
startingCash overrides the previously set amount and the override
is logged.

* Simplify SetAccountCurrency remarks and drop unused message
Tightens the XML remarks to two cases (different currency: keep previous
in its own entry; matching currency: override). Also removes the now
unused CannotChangeAccountCurrencyAfterSettingCash string since the
portfolio no longer throws.

* Simplify in-line comment in SetAccountCurrency
Drops the "Undo that migration" wording (residue from a previous fix
attempt) and just describes what the branch does: keep the previous
balance in its own currency entry while the new account currency starts
at zero.

* Differentiate implicit vs explicit SetCash on account currency switch
SetCash(decimal) is currency-agnostic: the amount is "this many units of
the (eventual) account currency". Switching the account currency now
re-labels the amount onto the new currency instead of preserving the
previous one. SetCash(symbol, ...) for the current account currency keeps
the old behaviour of preserving the balance in its own CashBook entry.
Splits the existing tests by overload and adds a starting-cash variant
for the explicit case.

* Mark base cash explicit on any SetCash(symbol, ...) call
Broaden _baseCashSymbolSetExplicitly so any call to the explicit-currency
overload signals the user is committing to named currencies, not just
calls whose symbol matches the current account currency. SetAccountCurrency
then preserves the previous base-currency balance in its own CashBook
entry whenever the user has touched the explicit overload at all.

* fix: support BNFCR alternative collateral in CryptoFutureMarginModel for Binance (#9339)
* refactor: use classic switch in BinanceFuturesBrokerageModel.GetBuyingPowerModel
* fix: CryptoFutureMarginModel in BinanceCoinFuturesBrokerageModel
* refactor: simplify BinanceCryptoFutureMarginModel collateral conversion
* fix: restore IsCryptoCoinFuture guard in BinanceCryptoFutureMarginModel
* refactor: simplify BinanceCryptoFutureMarginModel to direct BNFCR lookup
Replace IsStableCoinWithoutPair foreach loop with a single TryGetValue
check for BNFCR. BNFCR is EU/EEA-only (MiCA Credits Trading Mode) so
the lookup is a no-op for all other users. Amount reflects availableBalance
from the Binance API — the total cross-margin pool already aggregated by
Binance — making the > 0 guard correct and avoiding CashBook iteration.
* feat: add regression algorithm for BNFCR as sole collateral on Binance USDⓈ-M futures
Asserts end-to-end that EU/MiCA accounts with zero USDT and BNFCR as
the only collateral can open ADAUSDT positions. Verifies buying power,
holdings AbsoluteHoldingsCost, TotalSaleVolume, TotalMarginUsed,
maintenance margin consistency and TotalUnrealizedProfit accuracy.
* refactor: BNFCR presence gate with CashBook iteration for supplementary collateral
Replace IsStableCoinWithoutPair and hardcoded asset list with CashBook
iteration gated by BNFCR presence. Binance controls which assets are in
the account — all with non-zero walletBalance are valid collateral.
Add tests for BNFCR zero balance and BTC collateral conversion.
* refactor: aggregate all collateral without reference equality check
* fix: shared collateral deduction across quote currencies for EU/MiCA BNFCR mode
- Extract virtual SharesCollateral in CryptoFutureMarginModel
- Override in BinanceCryptoFutureMarginModel: BNFCR present → all USDⓈ-M share pool
- Add BNFCRCurrency const
- Add SharedCollateralDeductsMaintenanceMarginAcrossQuoteCurrencies unit test
- Refactor regression algorithm to assert shared collateral across ADAUSDT/ETHUSDC
* refactor: remove dead IsCryptoCoinFuture guard from BinanceCryptoFutureMarginModel
- Remove IsCryptoCoinFuture() check (coin futures use BinanceCoinFuturesBrokerageModel, not this model)
- Call base.GetTotalCollateralAmount() instead of duplicating primaryCollateral.Amount
- Remove CoinFutureDoesNotIncludeBnfcrAsCollateral test (tested wrong margin model)
* refactor: make GetCollateralCash private in CryptoFutureMarginModel
- No longer accessed by subclasses after removing direct collateral checks from BinanceCryptoFutureMarginModel
