feat: 个人中心仪表盘视觉打磨与交互优化

本次提交对个人中心（Profile Dashboard）进行了全面的 UI/UX 升级：

## AppShell 导航修复
- 修复浮动导航栏显示逻辑：移除未登录状态下多余的 session 判断条件，确保登录页不显示导航

## ProfilePage 功能增强
- 新增面板标题、描述和计数变量，动态展示不同面板（代表作/服务器项目/我的资产/社区审核）的上下文信息
- 背景图更换按钮增加 aria-label 无障碍支持，文字使用独立 span 便于移动端隐藏
- 积分与任务切换按钮拆分为标签+数值结构，信息层级更清晰
- 账号摘要卡片新增套餐名称和已完成任务数展示
- 操作按钮（工作台/社区/退出登录）包裹至 actions 容器，统一布局管理
- 主面板标签页文字包裹 span，支持响应式隐藏

## profile.css 滚动模型调整
- Dashboard 视图改用页面自然滚动，替代嵌套区域滚动，避免双滚动条问题

## dark-green.css 主题样式（约 1160 行新增）
- 背景图与头像区域：毛玻璃按钮、头像环绿边光晕、hover 编辑覆盖层
- 个性签名：圆角胶囊展示态 + 编辑态双向布局，状态提示条
- 账号卡片：标签按钮网格化布局、积分摘要面板、套餐标签
- 操作按钮组：主按钮渐变绿色、次要按钮低对比、退出按钮红色警示
- 内容标签页：胶囊切换 + 计数徽章，激活态绿边高亮
- 列表卡片：hover 微上浮 + 绿色边框过渡，空状态虚线面板
- 多轮视觉迭代：从 graphite 灰调到最终 black+green 参考色调
- 响应式适配：移动端头像环缩小、背景按钮圆形、标签页紧凑排列
- 页面级滚动：让 body 自然滚动，取消 content 内部滚动容器
