+/// Fetches the current authenticated user's member card.

+/// Usage:
+/// ```dart
+/// final memberCard = await getMemberCard();

+///
+/// This use case:
+/// - Retrieves member card from repository (which handles caching)
+/// - Can add business logic if needed (e.g., validation, transformation)
+/// - Returns MemberCard entity

+  /// Returns [MemberCard] with user's membership information.

+  /// - [UnauthorizedException] if user not authenticated
+  /// - [NetworkException] if network error occurs
+  /// - [CacheException] if local data corrupted

+  /// - Cached data is known to be stale
+  /// - After points redemption or other updates
