1) 行位图缓存键漏了插入符与选区：信号列表整行走 PaintRowCached，RowCacheKey
在编辑态只混合“是否编辑 + 文本” ⇒ 左右方向键与鼠标框选虽然改变了 TextEdit
状态（caret/anchor），键却不变 ⇒ 贴回旧位图。表现就是“无法部分选择、
鼠标框选无反应、光标不动”，而绘图区的光标时间输入（无行缓存）一直正常。
修法：GROUP_TITLE / SIGNAL_NAME 两个分支编辑态把 Caret / SelectionBegin /
SelectionEnd 一并 mix 进键；新增 SignalPanel::EditFieldFont() 统一
绘制（uiSmall / ui）与鼠标命中、插入符换算所用字体。
2) Theme / PaintUtil / TextEdit / PopupMenu / ColorPickerPopup 由
Utilities/{Inc,Src} git mv 到 Components/Shared/{Inc,Src}：
Utilities 只保留纯数据/逻辑模块（DataModel、DataTable、各 *Loader、MatH5、
Utf8Util），Shared 成为自洽的 UI 基础层（Theme → PaintUtil → UiControls →
PopupMenu / ColorPickerPopup）。依赖方向仍是 Components → Shared → Utilities；
PaintUtil 一并迁移是因为它依赖 Theme（否则构成 Utilities → Shared 反向依赖）。
Makefile 无需改动（include 平铺，两个目录都已在搜索路径），但需清理 Build/*
里对应的旧 .o/.d。
验证（全部离屏，不占用鼠标/键盘/屏幕）：
- 新增 .preflight/editcheck 20/20；A/B 修复前 6 项如实失败（键不变 + 屏幕不重绘）；
- 既有 .preflight/check 137/137；
- make release / make debug 零警告。
