Merge a card refresh (#59)

- **Refactored Card Placement Flow**
  - Separated card presentation from orchestration logic
  - Extracted `CornerCardManager` for pending card lifecycle (spawn, shuffle, rebuild)
  - Extracted `AlbumNavigationService` for book page navigation and zone mapping
  - Extracted `CardEnlargeController` for backdrop management and card reparenting
  - Implemented controller pattern (non-MonoBehaviour) for complex logic
  - Cards now unparent from slots before rebuild to prevent premature destruction

- **Improved Corner Card Display**
  - Fixed cards spawning on top of each other during rebuild
  - Implemented shuffle-to-front logic (remaining cards occupy slots 0→1→2)
  - Added smart card selection (prioritizes cards matching current album page)
  - Pending cards now removed from queue immediately on drag start
  - Corner cards rebuild after each placement with proper slot reassignment

- **Enhanced Album Card Viewing**
  - Added dramatic scale increase when viewing cards from album slots
  - Implemented shrink animation when dismissing enlarged cards
  - Cards transition: `PlacedInSlotState` → `AlbumEnlargedState` → `PlacedInSlotState`
  - Backdrop shows/hides with card enlarge/shrink cycle
  - Cards reparent to enlarged container while viewing, return to slot after

- **State Machine Improvements**
  - Added `CardStateNames` constants for type-safe state transitions
  - Implemented `ICardClickHandler` and `ICardStateDragHandler` interfaces
  - State transitions now use cached property indices
  - `BoosterCardContext` separated from `CardContext` for single responsibility

- **Code Cleanup**
  - Identified unused `SlotContainerHelper.cs` (superseded by `CornerCardManager`)
  - Identified unused `BoosterPackDraggable.canOpenOnDrop` field
  - Identified unused `AlbumViewPage._previousInputMode` (hardcoded value)
  - Identified unused `Card.OnPlacedInAlbumSlot` event (no subscribers)
