5 层 UI 规范收敛 SelectRoleForm 的 RawData / Context

围绕规范 §3.2 / §3.4 / §8 整理 SelectRoleForm 的数据传输与展示模型，让两层各自只承担规范允许的职责，并把子组件归位到模块目录内。

RawData层：
- RolePropertyAreaRawData 移除展示串 InitialPropertyText，改为业务字段 StatModifier[] InitialProperties，并补回 RoleId，避免 RawData 携带已格式化的展示文本（违反 §3.2）。
- SelectRoleRawData 拆掉平铺的 RoleIds / RoleIconNames 平行数组与 SelectedRoleId / SelectedRoleName / SelectedRoleInitialProperties 哨兵字段，聚合为 RoleItemRawData[] RoleItems 与 RolePropertyAreaRawData SelectedRole（null 表示未选中），跟 Context 端的子结构形态对称。
- SelectRoleUseCase.BuildModel 同步改造为构造子 RawData，不再处理 -1 哨兵 ID。

Context 层：
- 删除 SelectRoleContext.RoleIds 冗余字段（信息已由 RoleItemContexts[i].RoleId 承载）。
- 新增 bool ShowRoleProperty，把"显示属性卡 vs 显示随机卡"从 RolePropertyAreaContext == null 的隐式哨兵改成显式信号；Form 端 UpdateShowRole 改为读 ShowRoleProperty 切换卡片，不再用 null 当三态信号。
- Controller.BuildContext 用 rawData.SelectedRole != null 取代 >= 0 判定，InitialPropertyText 仍由 Controller 通过 ItemDescUtility.CreatePropDescription 拼装后注入 Context。
