feat: 个人中心账户摘要区重构、主题色调对齐电商

【账户摘要区重构】
- 新增 profile-page__account-summary 双列网格布局（主信息 + 右侧指标）
- 主信息区（account-summary-main）：显示账号名/任务概览
- 指标区（account-summary-metric）：品牌绿色数字展示积分/完成数，左侧分隔线
- 任务概览改为"X 个任务"更自然的表达方式
- 替代旧 upload-card--meta/meta-item 类名体系

【主题色调对齐】
- 个人中心页面背景、侧边栏、卡片统一为电商同款平坦暗色
- 移除 box-shadow 深度阴影，使用 var(--bg-panel)/var(--bg-inset) Token
- Tab 切换按钮透明背景，选中态品牌绿边框+浅绿背景
- 统计卡片/简介/Bio/媒体预览卡片统一边框与背景色
- 媒体徽章、分享按钮、头像环去除阴影
