Felizv3

[Sagensagen]

Migrates from Feliz 2.x to Feliz 3.2.0, updating internal APIs
that were removed or changed in Feliz 3.

Feliz 3.x compatibility

• Replace Interop.reactApi.Children.toArray with Array.ofSeq across Props.fs,
  Props2.fs, and FelizProps.fs (18 occurrences)
• Replace Interop.mkAttr → PropHelper.mkAttr and Interop.mkStyle →
  StyleHelper.mkStyle in the FelizOverloads module
• Add Interop.reactElementWithChildren helper to Utils.fs

Fix createElement children handling

• FuiHelpers.createElement now extracts children from props and passes them
  as spread arguments to React.createElement, matching how Feliz 3.x handles it.
  Uses Feliz.HtmlHelper.extractByKeyFast for extraction.
• This fixes React "missing key" warnings that occurred because children were
  being passed as an array inside the props object.
• Fix TeachingPopoverTrigger Fragment runtime error by using
  reactElementWithChildren instead of createElement with prop.children.

Fable 5 compatibility

• Replace interpolated string imports in BundleIcons.fs and FluentUI.fs icon
  imports with importAll + emitJsExpr dynamic access, since Fable 5 requires
  string literals for import.

Feliz 3.x + fable 4.x had some breaking changes, and required either to add aNoWarn NU1605, or to upgrade to fable 5 prerelease. Therefore took a long shot and went with Fable 5 since it seems it is maturing.

It works perfectly fine with fable 4 as well, if stable fable version is preferred.

Package updates

• Feliz 2.x → 3.2.0
• Added Fable.Core 4.5.0
• V8toV9: removed Interop.reactApi.Children.toArray, uses Array.ofSeq
