Summary:

Fixes #58758.

Apps built with the iOS 27 SDK can no longer change the status bar through the UIApplication setters. Restore the view-controller-based implementation: RCTStatusBarAppearance stores the requested style, hidden state and animation, and the default root and Fabric modal controllers return those values. The modal preserves the appearance captured before presentation until JavaScript changes it.

Apps must set UIViewControllerBasedStatusBarAppearance to YES on iOS 27. Custom root view controllers must return the RCTStatusBarAppearance values. Apps using NO retain the legacy setters on older SDKs and receive a one-time warning where those setters are ineffective.

Exclude the appearance helper and status-bar controller code on tvOS, where UIKit's status-bar types and APIs are unavailable. Guard the modal capture declaration and call as well as its state and implementation. The iOS code paths are unchanged.

Test Plan:

• Built the full AirwaveBurbn app and package for appletvos-arm64 with the Airwave mode, local build flavour, Pika 27 and Xcode 27.1. Code signing was skipped for local validation. Both targets passed. Buck run: https://www.internalfb.com/buck2/9c21f926-63ea-4fd5-8370-286f70fc829b.
• Built ReactApple, RCTFabricApple and RCTAppDelegateApple with AirwavePlatform-appletvos-arm64-local. All passed. Buck run: https://www.internalfb.com/buck2/0aaabc5f-e893-4d9d-8ce1-a346c3315bbf.
• Built ReactApple, CoreModulesApple, RCTFabricApple and RCTAppDelegateApple for iphonesimulator-arm64. All passed. Buck run: https://www.internalfb.com/buck2/876de6d7-fbd8-439f-bdbe-d4fed3d29a91.
• Regenerated all C++ API snapshots. Only the four ReactApple snapshots changed, each adding RCTStatusBarAppearance; no private API appeared. Ran the snapshot target with --validate; all 12 snapshots passed. Validation run: https://www.internalfb.com/buck2/a8fc85da-ba96-4b3b-a741-afede29b5f0d.
• Meta-managed clang-format, arc f and arc lint passed.
• Independent read-only review found no blockers in the tvOS guards and confirmed that the iOS implementation matches the original landed change apart from platform guards.
• Restored the original 12 RCTStatusBarAppearanceTests XCTest cases. These remain registered in the OSS Xcode test target, have no internal Buck owner, and were not run locally. No simulator runtime verification was performed.
• The manual Sandcastle smoke launcher defaulted to iphoneos rather than appletvos. Its build and baseline retry failed target-compatibility checks before compiling. Do not count the launcher success as a passing tvOS build; the full tvOS validation is the local Buck run above. Child run: https://www.internalfb.com/intern/sandcastle/instance/40532397437851209/.
• Diff-time CI currently has a non-bypassable github-export-checks failure because this new diff has no linked/exported GitHub PR. Export at https://www.internalfb.com/intern/opensource/export/preview/D127817413/ and rerun the check before landing. Other CI jobs are still running.
• General Reviewer flagged a modal-state edge case also present in the original patch: changing a JS status-bar value and then returning to its capture-time value can restore the pre-modal native appearance. That warning remains unresolved for review; this re-land deliberately preserves the original iOS behaviour.
