fix(wilderness): 修复 Act 1 荒野关卡内部连通性与通路屏障 (Issue #79)

- 将 Act 1 荒野道路地面瓦片由 style 5 (在 Town/Floor.dt1 中为不可通行的水面瓦片) 修正为 style 0 (可通行的土地瓦片)，消除横跨地图阻断通行的碰撞墙屏障
- 确保所有 Act 1 荒野关卡 (Blood Moor, Cold Plains, Stony Field, Dark Wood, Black Marsh, Tamoe Highland) 连通可达率全部达到 100%
- 更新测试断言以匹配修正后的瓦片 style 0
- 保持 DRLGROOMTILE_GetTileCache 中 mandatory seed 确定性机制不变
