* Fix MaximumSharpeRatioPortfolioOptimizer to maximize the Sharpe ratio
The optimizer fixed the portfolio return to the equal-weight return
((µ − r_f)ᵀw = k) and minimized variance, which collapsed it to a
minimum-variance optimizer instead of maximizing the Sharpe ratio.
Python now maximizes (µ − r_f)ᵀw / √(wᵀΣw) directly with SLSQP, keeping
the budget constraint Σw = 1 and the per-weight bounds. C# applies the
Charnes-Cooper substitution y = κw, minimizing yᵀΣy subject to
(µ − r_f)ᵀy = 1 and recovering w = y / (1ᵀy); the per-weight bounds are
written as linear constraints in y (yᵢ − up·(1ᵀy) ≤ 0, yᵢ − lw·(1ᵀy) ≥ 0)
so the problem stays a convex QP and the [lower, upper] range is honored.
Both languages reach the same optimum, and the unit-test expectations are
updated to the corrected weights.
Addresses QuantConnect/Lean#9322

* Solve bug and add regression test
The bug was raised because, when trying to use C#
MeanVarianceOptimizationPortfolioConstructionModel from a Python
algorithm, there wasn't a constructor that accepted a portfolio optimizer
as a PyObject. Additionally, there wasn't also a Python Wrapper to wrapp
that portfolio optimizer.
- Add PortfolioOptimizerPythonWrapper.cs
- Add constructor in
MeanVarianceOptimizationPortfolioConstructionModel.cs that accepts
portfolio optimizer as a PyObject
- Add regression algorithms to cover the changes
* Improve constructor overload implementation
* Change implementation to follow API pattern
* Enhance implementation and add unit tests
* Enhance implementation and add more unit tests
* Enhance implementation
* Improves MinimumVariancePortfolioOptimizer Values Handling
The C# version of the `MinimumVariancePortfolioOptimizer` generated NaN resulting in unit tests failing.
If the solver returns NaN for an item, we set it to zero. if all items are NaN or Zero, we return the initial guess, since the sum cannot be zero.
* Fixes `RiskParityPortfolioConstructionModelTests`

* Asserts Number of Insights In One PCM Regression Test

* Refactor Portfolio Construction Models to Use Insight Manager
`PortfolioConstructionModel` will use `QCAlgorithm.Insights" instead of class property `InsightCollection` to manage the insights. It no longer adds insights to the collection, but it removes them if they expire or the securities are removed from the universe.
Updates PCMs that were affected by the change.

* Updates Regression Tests 2
The following regression tests were adapt because of verification of hard-coded market data values:
- `AdjustedVolumeRegressionAlgorithm`
- `HistoryWithSymbolChangesRegressionAlgorithm`
- `OptionRenameRegressionAlgorithm`
- `RawDataRegressionAlgorithm`
- `SwitchDataModeRegressionAlgorithm`
The following regression tests have more trades since adjusted prices allowed more 1-2 shares trades that were rounded down to zero before:
- `AddUniverseSelectionModelCoarseAlgorithm` 23 -> 35
- `MeanVarianceOptimizationFrameworkAlgorithm` 12 -> 14
- `PortfolioRebalanceOnDateRulesRegressionAlgorithm` 298 -> 324
- `PortfolioRebalanceOnInsightChangesRegressionAlgorithm` 83 -> 86
- `ScheduledUniverseSelectionModelRegressionAlgorithm` 86 -> 90
- `SectorExposureRiskFrameworkAlgorithm` 17 -> 22
- `SetHoldingsMultipleTargetsRegressionAlgorithm` 8 -> 9
- `StandardDeviationExecutionModelRegressionAlgorithm` 196 -> 199
- `UniverseUnchangedRegressionAlgorithm` 11 -> 17
- `VolumeWeightedAveragePriceExecutionModelRegressionAlgorithm` 237 -> 238
Especial cases:
- `BlackLittermanPortfolioOptimizationFrameworkAlgorithm` 18 -> 17
- BLM model sensibility
- `OptionChainedAndUniverseSelectionRegressionAlgorithm`
The following regression tests have different Capacity because of different volume from lowest capacity asset, except:
- `OptionEquityCoveredCallRegressionAlgorithm` New lowest capacity asset is underlying
- `OptionEquityCoveredPutRegressionAlgorithm` New lowest capacity asset is underlying
* Revert File Update for SPWR and SPWRA
* Fix Regression Tests
Temporarily removes python regression test for `MeanVarianceOptimizationFrameworkAlgorithm` as the `MeanVarianceOptimizationPortfolioConstructionModel` for each version are yeilding different results. If we use C# version in `MeanVarianceOptimizationPortfolioConstructionModel.py`, the results match.
* Changes Optimization Method in MinimumVariancePortfolioOptimizer [Py]
Uses `trust-constr` method.

- Fix out of range exception, if the returns array is smaller for some
of the Symbols it will use double.NaN, similar behavior to when a date
isn't found for a Symbol. Adding unit test
- Fix duplicate key exception at ReturnsSymbolData.Returns, this could
happen with FF in history requests. Adding unit test
When new securities are added to the universe, the `ReturnsSymbolData` is warmed up with historical data that may not have the same timestamp causing an index mismatch that leads to a rejection to several valid data. In this case, we will assume that there is a time correspondence similar to what is done in Python. Unit test was added.
`BlackLittermanOptimizationPortfolioConstructionModel` will consider a new view only if there is a new last active insight by updating the `ReturnsSymbolData` with the `Insight.GeneratedTimeUtc` instead of the `IAlgorithm.Time`. Consequently, the timestamp of the historical data is converted to UTC for consistency.
`BlackLittermanSymbolData` now rejects duplicate keys like its C# version: `ReturnsSymbolData`.
Finally, `BlackLittermanPortfolioOptimizationFrameworkAlgorithm` statistics was updated because of the bug fixes.
- Reduce MinimumVariancePortfolioOptimizar precision goal so that both
CSharp and Py MeanVarianceOptimizationFrameworkAlgorithm return the same
results
- Limit factor file dates in factor file generator unit test
Implements `PortfolioBias` in EWPCM, CWPCM and IWPCM. With this new feature, these PCM will ignore insights that do not respect the desired bias. E.g. for `PortfolioBias.Long`, on Insights with `InsightDirection.Up` will be converted into `PortfolioTarget.Quantity` greater than zero and other `InsightDirection` will result in `PortfolioTarget.Quantity` of zero.
- Adding new unit test for python PCM implementations, asserting each
method is correctly called
- Reverting some unrequired changes in the
`MeanVarianceOptimizationFrameworkAlgorithm`
- Refactor shared logic from `EqualWeightingPortfolioConstructionModel`
into base `PortfolioConstructionModel` implementation
- `MeanVarianceOptimizationPortfolioConstructionModel` will respect
rebalancing period and will use all active inisights, not just the last
