Improve maze start/end placement with dead-end detection

Refactored PlaceStartAndEnd to intelligently place start and end points at dead ends using random selection and distance-based fallbacks. Added EnforceSingleConnection to ensure start/end points have exactly one connection, compatible with U-turn prefabs. Improved MazeReworkSpawner with object hierarchy grouping (Floors, Categories) and made RefreshSingleCell public. Updated maze config and cleaned up scene hierarchy.
