Fixes#31. All trees, rocks, seedlings and buildings now use
tileY+5 as depth instead of a fixed value, so objects further
down the screen always render in front of objects above them
regardless of spawn order. Build ghost moved to depth 1000/1001.

CHANGE_TILE only called worldSystem.setTile() (built-tile layer only),
never refreshTerrainTile() — so chopped trees stayed visually dark-green
(FOREST color) even though the tile type was already DARK_GRASS.
- adapter.onAction for CHANGE_TILE now also calls refreshTerrainTile()
→ all tile transitions (chop, mine, seedling maturation) update the
canvas pixel immediately and consistently in one place
- Remove now-redundant explicit refreshTerrainTile() call in
TreeSeedlingSystem (the adapter handler covers it)
- Tile-recovery path in GameScene (stateManager.tickTileRecovery) is
NOT routed through the adapter, so its manual refreshTerrainTile()
call is kept as-is
