laoyang c69f4461dc 科技报告配色统一为幻灯片同一套海大标准色 #5
改前用的是 xcolor 通用色,跟海大无关:notebox 用 NavyBlue、importantbox
用 Orange、代码关键字纯蓝 rgb(0,0,1)、注释纯绿、代码标题 violet、水印纯灰。
同一个学校两个模板的「蓝」和「红」不是一回事。

新增 cls/color.cls 作为唯一配色入口:
- 10 个基色与 幻灯片/theme/beamercolorthemeOUCSlide.sty 逐值相同
  (前 7 个是官方 2021 版 VI 标准色,后 3 个是幻灯片补充的第三色)
- 8 个语义词别名(oucprimary / oucaccent / oucinfo / oucalert /
  ouccaption / oucrule / ouclink / oucmuted),按语义引用而非色名,
  将来调色只改一行
- 代码配色从标准色派生:关键字→海大蓝、注释→苍松绿、
  字符串→海大红、类型→海大天蓝、边框→专银

各文件改为引用语义色,不再硬写 RGB:
- boxes.cls:notebox NavyBlue→oucinfo,importantbox Orange→oucalert
- code.cls:删掉本地 5 个 definecolor;bashstyle NavyBlue→oucblue;
  bashoutputstyle black!10→codecolorbg + 专银线;行号 gray→oucmuted;
  代码标题 violet→ouccaption
- hyperref.cls:硬写 black→ouclink
- setting.tex:水印纯灰→海大蓝 4%(原 Lightness 会强制切 gray 模型覆盖颜色,已去掉)
- report.cls:加 \input{cls/color.cls},必须有在 boxes/code 之前

有意保持中性的两处(已在注释里说明理由):
- shellbox / invertedshellbox:终端反白块语义就该是黑底,
  换成蓝会变成「强调块」抢正文注意力
- 页眉线:彩色页眉线会跟正文海大蓝标题抢视觉层级,仍 0.5pt 黑

验证:错误 0,10 页,Overfull 0,Underfull 保持既有 2 条;
PDF 逐 span 提取文字色只剩 #004098 / #C81528 / #000000,
矢量填充与描边全部落在标准色内,无 NavyBlue / Orange / violet 残留。
