feat(partners): add dedicated Railway Gold partner landing page (#925)

* feat(partners): add dedicated Railway Gold partner landing page

Replaces the generic `partners.$partner` template for Railway with a
purpose-built landing route at `/partners/railway`, in line with the
Gold-tier sponsorship agreement.

The page is built almost entirely from existing tanstack.com primitives
to stay visually and behaviorally consistent with the rest of the site:

- `CodeBlock` (Shiki) for the config and terminal snippets (replaces a
  hand-rolled `<pre>` which inherited the global `text-black` rule and
  rendered invisible on dark backgrounds)
- `Card` for feature, step, library-fit, pricing and testimonial panels
- `Button` (`as="a"`) for every CTA, with brand-tinted overrides on the
  hero and dark CTA section
- `Collapsible` / `CollapsibleTrigger` / `CollapsibleContent` for the
  FAQ accordion, controlled by a parent `openFaq` state so only one
  answer expands at a time
- `seo()` for title/description/OG/Twitter Card meta
- Existing `PartnerImage` and `railway-{black,white}.svg` brand marks
  for the hero

SEO additions:

- Page-specific title + description targeting "deploy tanstack to
  railway" and related queries
- Two `application/ld+json` blocks in SSR: the existing partner
  `WebPage` schema plus a new `FAQPage` schema generated from the
  on-page FAQ for Google rich results + AI search agents

Analytics:

- Fires `partner_viewed` on mount with `placement: 'detail'`
- Fires `partner_clicked` with `destination_host: 'railway.com'` on
  every outbound Railway CTA, matching the existing taxonomy in
  `analytics/events.ts`

All outbound Railway links carry
`utm_medium=sponsor&utm_source=tanstack&utm_campaign=partner-page`.
The static `/partners/railway` route takes file-routing precedence
over the parametric `/partners/$partner` template, so the legacy
template is preserved untouched for every other partner.

* feat(partners/railway): polish copy + add mid-page CTAs

Voice + conversion pass before shipping. The hero, feature cards, and
section headings now match TanStack's restrained, pragmatic tone instead
of echoing Railway's own marketing site.

Copy changes:

- Hero paragraph rewritten using the same framing as
  `partnerGuidance.railway` in `partner-pages.ts` (drop "all-in-one
  intelligent cloud platform trusted by 2M+ developers" — that's
  Railway's tagline, not TanStack's voice)
- Feature card descriptions tightened to be outcome-focused
  ("No YAML to maintain.", "Test routing, data, and server logic
  before merging.")
- Replace emoji feature icons with Lucide icons (Rocket,
  GitPullRequest, LineChart, Network, Undo2, ShieldCheck, Globe,
  Infinity) to match the site's icon language
- Testimonial section heading "Teams are saving big on infrastructure"
  → "What teams say after switching" + a neutral framing line

CTAs:

The page previously had only the hero CTA + final CTA section, leaving
~6 content sections between them with no out-link. Added three mid-page
CTA blocks and varied the labels so no two CTAs read the same:

- Hero primary: "Deploy free in 2 minutes" (+ "No credit card · $5 in
  trial credits on signup" microcopy)
- After how-it-works code blocks: "Try the Railway preset" + "Read the
  deployment guide"
- After pricing tiers: "Start with $5 in credits" + "Estimate your
  costs" (new link to railway.com/pricing)
- After testimonials: "Move your app to Railway" + per-second-billing
  microcopy
- Final CTA: "Deploy your TanStack app" + "Open the docs"

Outbound railway.com links: 4 → 9, all distinct labels, all carrying
the partner-page UTM.

* fix(partners/railway): use the canonical @tanstack/cli scaffolder

Step 01 was `npx create-tsrouter-app my-app`, which is the older
router-only scaffolder. The TanStack Start docs recommend the unified
CLI for new apps, so match the official getting-started instructions.
