Introduce ApplePods.Flags and UI for key status

This commit introduces a new `Flags` data class within `ApplePods` to store boolean flags related to the device, specifically `isIRKMatch`.

This flag is now passed during the creation of `ApplePods` instances in all `ApplePodsFactory` implementations and the central `AppleFactory`.

The UI has been updated to display a key icon in the overview cards (`DualPodsCardVH` and `SinglePodsCardVH`):
- The icon is only visible if `flags.isIRKMatch` is true.
- The icon changes to a filled key (`ic_key_24`) if `payload.private` is not null (indicating successful decryption), otherwise an outline key (`ic_key_outline_24`) is shown.
- Minor layout adjustments were made in `overview_pods_single_item.xml` and `overview_pods_dual_item.xml` to accommodate the new key icon.
