RolesPermissions
TsgcHTMLComponent_RolesPermissions — 一个角色/权限矩阵，每个单元格带复选框，支持分类分组和实时 WebSocket 授权更新，适用于 Delphi、C++ Builder 和 .NET。
TsgcHTMLComponent_RolesPermissions — 一个角色/权限矩阵，每个单元格带复选框，支持分类分组和实时 WebSocket 授权更新，适用于 Delphi、C++ Builder 和 .NET。
添加角色和权限，设置初始授权，然后读取 HTML 属性。每次复选框切换都会发送到服务器，服务器必须先授权才能应用。
TsgcHTMLComponent_RolesPermissions
Bootstrap 5 表格矩阵 + 内联脚本
Delphi, C++ Builder, .NET
调用 AddRole 和 AddPermission 构建矩阵的两个轴，用 SetGrant 设置初始勾选状态，然后读取 HTML。

AddRole(aId, aName) 和 AddPermission(aId, aName, aCategory) 构建矩阵的两个轴；每个角色都有一个彩色徽章，每个权限都有一个可选的分类标题。
SetGrant(aRoleId, aPermissionId, aGranted) / GetGrant 以角色 + 权限 id 为键，读写勾选的单元格。
LoadRolesFromDataSet、LoadPermissionsFromDataSet 和 LoadGrantsFromDataSet 直接从 TDataSet 填充矩阵。
每次复选框切换都会通过 WebSocket 通道发送 JSON 负载，并触发 DOM 事件 sgcRolesPermissions:grantChanged。
ShowDescriptions、ShowCategories、Striped、Bordered、Compact 和 StickyHeader（配合 MaxHeight）设置表格样式；ReadOnly 禁用所有复选框。
此组件仅渲染 UI。只有在宿主程序在服务器端验证操作用户有权更改该角色/权限组合之后，才能调用 ProcessGrantChanged。
