fix: [IOAPPX-479] Fix camera permission request on Android devices

[mastro993]

Short description

This PR refactors the camera permission request logic on Android to align with the platform-specific behavior.

Detailed description

On Android, camera permission handling logic differs from iOS. When the app checks the permission status for the first time it receives a "denied" response, but this does not necessarily mean that the user has explicitly denied access and it simply can indicate that the permission has not been requested yet.
To address this, we decided to show the permission prompt as soon the user navigates to the barcode scanner screen.

This change only addresses Android, the logic remains unchanged on iOS.

List of changes proposed in this pull request

• Added useCameraPermissionStatus hook to separate camera permission request logic from useIOBarcodeCameraScanner
• On Android, if the camera permission is "denied", the app requires camera access as soon the user navigates to the barcode scanner screen
• Added a LoadingSpinner to BarcodeScanBaseScreenComponent when the camera permission is undefined

How to test

With an Android device: navigate to the barcode scanner screen and verify the following behaviors:

• On the first visit, the screen should display the system camera permission prompt
• After clicking "Deny", the screen should display the "Access denied" component with a "Go to Settings" button
• After enabling camera access in the device settings and returning to the app, the camera view should be displayed correctly

With an iOS device: navigate to the barcode scanner screen and verify that there aren't regressions.
