KMP SDK: Improve Robustness of Access Point Feature

[tcamise-gpsw]

This pull request includes several updates to improve the Kotlin multiplatform SDK, with key changes to upgrade the JVM target, enhance the AccessPointViewModel functionality, and refactor the GoProFacade class. Additionally, it introduces UI updates for better error handling and disconnect functionality, and includes dependency updates.

JVM Target Upgrade:

• Updated JVM target from JVM_11 to JVM_17 across multiple build.gradle.kts files for better compatibility and performance.

ViewModel Enhancements:

• Added _errorMessage and setErrorMessage for improved error handling in AccessPointViewModel. ([demos/kotlin/kmp_sdk/composeApp/src/commonMain/kotlin/presenter/AccessPointViewModel.ktR35-R110](https://github.com/gopro/OpenGoPro/pull/781/files#diff-0b0ad7c418548276414f4ac51508cf5e3861c06d820e4b7d625c14ca1a1f038fR35-R110))
• Replaced direct state updates with setState for better encapsulation. ([demos/kotlin/kmp_sdk/composeApp/src/commonMain/kotlin/presenter/AccessPointViewModel.ktR35-R110](https://github.com/gopro/OpenGoPro/pull/781/files#diff-0b0ad7c418548276414f4ac51508cf5e3861c06d820e4b7d625c14ca1a1f038fR35-R110))
• Introduced a disconnect method and updated scanForSsids and connectToSsid methods to use the new state management approach. ([demos/kotlin/kmp_sdk/composeApp/src/commonMain/kotlin/presenter/AccessPointViewModel.ktR35-R110](https://github.com/gopro/OpenGoPro/pull/781/files#diff-0b0ad7c418548276414f4ac51508cf5e3861c06d820e4b7d625c14ca1a1f038fR35-R110))

UI Updates:

• Integrated SnackbarMessageHandler to display error messages in AccessPointScreen. ([demos/kotlin/kmp_sdk/composeApp/src/commonMain/kotlin/ui/screens/connected/AccessPointScreen.ktR43-R49](https://github.com/gopro/OpenGoPro/pull/781/files#diff-7c4ffd2eea7dd10eb02354b6813b92b5f07547ff0cf66e0f2f1dca0de2e6b8e4R43-R49))
• Added a "Disconnect" button and corresponding functionality to ScanScreen for better user control. ([[1]](https://github.com/gopro/OpenGoPro/pull/781/files#diff-7c4ffd2eea7dd10eb02354b6813b92b5f07547ff0cf66e0f2f1dca0de2e6b8e4L64-R78), [[2]](https://github.com/gopro/OpenGoPro/pull/781/files#diff-7c4ffd2eea7dd10eb02354b6813b92b5f07547ff0cf66e0f2f1dca0de2e6b8e4R100-R104))

Refactor of GoProFacade:

• Removed GpDescriptorManager and refactored accessPointState and cohnState to directly use feature states. ([[1]](https://github.com/gopro/OpenGoPro/pull/781/files#diff-6a41897cd99e32876d9d1e713d2e777bccc442a7074a3c1ed7ada85321552e6aL65-L74), [[2]](https://github.com/gopro/OpenGoPro/pull/781/files#diff-6a41897cd99e32876d9d1e713d2e777bccc442a7074a3c1ed7ada85321552e6aL88-R78), [[3]](https://github.com/gopro/OpenGoPro/pull/781/files#diff-6a41897cd99e32876d9d1e713d2e777bccc442a7074a3c1ed7ada85321552e6aL108-R98))

Pull Request Overview

This PR enhances the robustness of the Access Point and COHN features by introducing state flows, retry logic, and better error handling, and updates JVM targets to Java 17 across modules.

• Introduce MutableStateFlow/StateFlow for both CohnFeature and AccessPointFeature to track feature state.
• Add retry (robustlyConnect) and timeout logic for AP connections, and streamline COHN provisioning flows.
• Refactor GoProFacade to surface feature state directly, remove outdated descriptor manager, and bump JVM compatibility to 17.
