p77: 日历卡/浮动提示药丸化并修复面板遮挡快捷栏

- DrawCalendarCard 改半透明底+1px 描边+accent 发丝线，日历卡微缩(52→48)
- FloatingPrompt 新增 layoutWrapped/wrapText，锚定长文本逐字折行(不丢字、居中锚点、避让 HUD 带)
- 新增 HudLayout.panelRect，DrawPanel 用其几何；DialogOverlay.bottomMargin 24→72
  1280x720 下对话 rect 底 648、任务面板底 652，均 < hotbar 顶 660，不再压 3-8 号槽
- 新增 P77LayoutTests(4 尺寸不破版/不遮挡 + 真实长提示折行)
- 证据 LV_P43/P44/P67_SHOT + scripts/analyze-p77.py(verdict PASS) 落 docs/evidence/p77-*
- Desktop 361/361, Kernel 120/120, digest 953775FA...F7F6C 不变
