fix(device_info_plus): update iOS/macOS deployment targets to 15.0 and fix isiOSAppOnVision detection

[Melsaeed276]

Description

This PR updates the minimum deployment targets and improves the isiOSAppOnVision detection:

• iOS: Updated minimum deployment target from 12.0 to 15.0
• macOS: Updated minimum deployment target from 10.14 to 15.0
• iOS App on Vision detection: Changed from compile-time @available(iOS 26.1, *) to runtime detection using @available(iOS 15.0, *) + @available(iOS 26.1, *) + respondsToSelector:. This ensures the isiOSAppOnVision property is correctly detected at runtime without causing compile-time warnings on older SDKs.

Since the podspec now sets the minimum iOS deployment target to 15.0, the outer @available(iOS 15.0, *) check is redundant (all supported runtimes satisfy it) and adds unnecessary nesting. Consider removing the iOS 15 availability guard and keeping only the version/selector checks that can actually vary at runtime.

Suggested change

	if (@available(iOS 15.0, *)) {
	if (@available(iOS 26.1, *)) {
	if ([info respondsToSelector:@selector(isiOSAppOnVision)]) {
	isiOSAppOnVision = [NSNumber numberWithBool:[info isiOSAppOnVision]];
	}
	if (@available(iOS 26.1, *)) {
	if ([info respondsToSelector:@selector(isiOSAppOnVision)]) {
	isiOSAppOnVision = [NSNumber numberWithBool:[info isiOSAppOnVision]];

[Copilot]

Raising the minimum iOS/macOS deployment targets is a breaking change for plugin consumers, but the PR title doesn’t include the Conventional Commits breaking-change marker (!) and the PR description’s breaking-change checklist is contradictory (both Yes and No checked). Please align the PR metadata (title/description) with the actual breaking nature of this change.
