Refactor parameter names and simplify iteration

Changed parameter name `innerResult` to `methodInnerResult` in `OnInnerResultCompleted` method across multiple files in the `Caliburn.Micro` namespace for consistency:
- `ContinueResultDecorator.cs`
- `OverrideCancelResultDecorator.cs`
- `RescueResultDecorator.cs`
- `ResultDecoratorBase.cs`

Removed unnecessary variable `keys` in `HttpUtility.cs` within the `Caliburn.Micro.Maui` namespace, directly iterating over `this.Keys` in the `foreach` loop to simplify the code.

Closes #940
Closes #939
