Pull request overview

This PR addresses missing badge rendering in the top toolbar when Liquid Glass is disabled on iOS 27 (notably when legacy layout is forced), and renames the “legacy tab bar” forcing flag/modifier to reflect its broader scope across navigation elements.

Changes:

• Update toolbar item rendering (including badges) to use legacy layout when either Liquid Glass is disabled or legacy layout is explicitly forced.
• Rename the environment flag/modifier from tab-bar-specific naming to broader “legacy layout” naming across navigation components.
• Update migration/documentation/changelog to reflect the rename and the iOS 27 + Xcode 26 edge case.

OUDS/Core/Components/Sources/_/ViewModifiers/LayoutModifiers/OUDSLegacyLayoutModifier.swift:63

• The migration docs instruct users to call .forceOUDSLegacyLayout(), but there is no View extension providing that API (only OUDSLegacyLayoutModifier). This creates a public-API/documentation mismatch and makes the rename guidance incomplete. Consider adding a View.forceOUDSLegacyLayout() helper and updating the EnvironmentValues doc comment to match the broader scope (not tab bar-specific).
  OUDS/Core/Components/Sources/_/ViewModifiers/LayoutModifiers/OUDSLegacyLayoutModifier.swift:24
• Doc comment has a few typos/grammar issues ("wether", "stils") and an unclear sentence that could confuse when this modifier is needed.
  OUDS/Core/Components/Sources/_/ViewModifiers/LayoutModifiers/OUDSLegacyLayoutModifier.swift:55
• This comment still references "legacy tab bar" even though the modifier/environment value is now broader (used by toolbars/nav bars too). Updating wording helps avoid confusion for API consumers.
