fix(docs): DocsView fidelity port (plan A)

Visual alignment with zip Docs.html (excluding 3-col layout):
- SVG hexagon logo (replaces ⬢ emoji)
- h2 cyan accent bar (::before 3px left strip)
- Models section: replace <ul> with structured table
  (provider badges with brand-color dots, OK/BETA status chips)
- Wrap all code blocks in .code-panel with:
  - traffic-light header + filename tab
  - 复制 button with clipboard API + 已复制 feedback

Kept intentionally different per Stage 1 decisions:
- Section 1 uses 'contact admin@puro.im' (not OAuth self-serve)
- Nav omits pricing / design-system links
- Codex CLI section preserved (Vue-only)
