Fix iOS CI build failure from mixed Kotlin/Objective-C inheritance in location requester

[Copilot]

build-ios fails in GitHub Actions at :shared:compileKotlinIosSimulatorArm64 due to Kotlin/Native rejecting mixed Kotlin and Objective-C supertypes in the iOS location requester implementation. This PR removes that invalid inheritance pattern while preserving existing location request behavior.

• Root cause

  • IosLocationRequester implemented both:
    • Objective-C delegate types (NSObject, CLLocationManagerDelegateProtocol)
    • Kotlin interface (LocationRequester)
  • Kotlin/Native reports: Mixing Kotlin and Objective-C supertypes is not supported.

• Code change

  • Updated shared/src/iosMain/kotlin/org/homefix/project/features/location/LocationRequester.ios.kt
  • Refactored to composition:
    • IosLocationRequester now only handles Objective-C delegate responsibilities.
    • rememberLocationRequester returns a LocationRequester wrapper that delegates request() to the Objective-C-backed instance.

• Behavioral impact

  • No feature change intended.
  • Location permission + update flow remains unchanged; only type hierarchy wiring was adjusted for Kotlin/Native compatibility.

actual fun rememberLocationRequester(onResult: (GeoPoint?) -> Unit): LocationRequester =
    remember(onResult) {
        val requester = IosLocationRequester(onResult)
        LocationRequester { requester.request() }
    }

private class IosLocationRequester(
    private val onResult: (GeoPoint?) -> Unit,
) : NSObject(), CLLocationManagerDelegateProtocol {
    fun request() { /* unchanged logic */ }
}

Pull request overview

This PR fixes the iOS CI failure in :shared:compileKotlinIosSimulatorArm64 by removing the unsupported Kotlin/Native inheritance pattern that mixed Kotlin and Objective-C supertypes in the iOS LocationRequester implementation, replacing it with a composition-based wrapper while keeping the same runtime behavior.

Changes:

• Refactored rememberLocationRequester on iOS to return a LocationRequester SAM wrapper that delegates to an Objective-C-only delegate class.
• Updated IosLocationRequester to implement only NSObject + CLLocationManagerDelegateProtocol (no longer implements the Kotlin LocationRequester interface).
• Adjusted request() on iOS from override fun request() to a plain fun request() to match the new delegation approach.
