* - 摇取点数：grid_number
* - 起始索引：start_index = DiceRewardConfig::where('grid_number', $grid_number)->first()->id
* - 结束索引（顺时针）：end_index = ($start_index + $grid_number) % 26（对 26 取余）
* - 结束索引（逆时针）：end_index = ($start_index - $grid_number >= 0) ? ($start_index - $grid_number) : (26 + $start_index - $grid_number)
* - 奖励档位：tier = DiceRewardConfig::where('id', $end_index)->first()->tier
* - 显示ui：ui_text = DiceRewardConfig::where('id', $end_index)->first()->ui_text
* - 实际中奖：real_ev = DiceRewardConfig::where('id', $end_index)->first()->real_ev
* - 备注：remark = DiceRewardConfig::where('id', $end_index)->first()->remark
* - 类型：type = DiceRewardConfig::where('id', $end_index)->first()->type（-2=唯一惩罚,-1=抽水,0=回本,1=再来一次,2=小赚,3=大奖格）
* - weight 默认 1，后续在权重编辑弹窗设置
*
* 例如顺时针摇取点数为 5 时：start_index = 配置中 grid_number=5 对应格位的 id，
* 结束位置 = (起始位置 + grid_number) % 26，再取该位置的 config 的 id 作为 end_index。
* 使用「按 id 排序后的盘面位置 0-25」做环形计算，避免 config.id 非连续时取模结果找不到；
* 唯一键为 (direction, grid_number)，保证每个点数、每个方向各一条记录，不因 end_index 相同而覆盖。
