fix: 提升暗色主题文字对比度，解决提示文字看不清的问题

- text-muted色值从#8b949e提亮到#9eaab8（对比度4.3:1→5.0:1） - 覆盖Bootstrap .text-muted默认色，统一走CSS变量 - 表单标签从text-muted改为text色+font-weight:500，更醒目 - 输入框placeholder设为#6e7a88，比默认更清晰 - .btn-secondary适配暗色主题，不再用Bootstrap默认灰 - modal-content显式设置color:var(--text) - index页新增.alert-info暗色适配 - 新增.form-text颜色覆盖
