refactor: slim graph node manager

Rebuilds the **Comfy MCP** marketing page on the website design-system
stack and adds the missing zh-CN page.

## What's here
- Replaces the bespoke `components/product/mcp/` section silo with thin
`templates/mcp/*` wrappers over reusable `blocks/` + `common/`
components.
- Adds `src/pages/zh-CN/mcp.astro` and threads `locale` through every
section (was English-only).
- New/extended design-system blocks:
- `FeatureGrid01` — setup steps, with a reusable `ui/CopyableField`
(uses `@vueuse/core` `useClipboard`).
- `FeatureGrid02` — how-it-works steps with `NodeUnionIcon` connectors +
a CTA pair via `ui/button`.
- `FeatureRows01` — alternating media rows; `ReasonsSplit01` — "why"
list.
- `HeroSplit01` gained `subtitle`, a `media` slot, and a `class`
passthrough; `SectionHeader` gained `align`.
- Standardized block section spacing on `px-6 py-16 lg:py-24`.
- Refreshed all 8 MCP FAQ answers (en + zh-CN) and hydrated the FAQ
section so the accordion is interactive.

## Notes
- Stacked on the original MCP landing-page commits (previously PR
#13095); those ride along here.
- `typecheck` and `build` are green; `/mcp` and `/zh-CN/mcp` both render
in both locales.
