chore(revenue-analytics): add deprecation banner and hide promo surfaces

[rafaeelaudibert]

Summary

Mirrors PostHog/posthog#59917 on posthog.com. Revenue analytics is being deprecated — the dashboard will be removed on or after June 30th, 2026. This PR adds the deprecation notice to our docs and hides Revenue analytics from product listings, navigation, cross-sell playbooks, and other promotional surfaces.

Docs deprecation banner

• Replace the legacy "beta warning" snippet at contents/docs/revenue-analytics/_snippets/rev-analytics-beta-warning.mdx with a deprecation CalloutBox (type="caution"). The snippet is already included across all the Revenue analytics docs pages, so every page now shows the notice.
• Add the same CalloutBox to the docs hub at src/pages/docs/revenue-analytics.tsx.

The banner copy mirrors the language used in the in-product banner: we're not stepping away from revenue, we're refocusing on exposing revenue properties on persons and groups so any insight, SQL query, or PostHog AI / MCP agent can build the right dashboard per use case.

Removed from product/marketing surfaces

• Deleted src/pages/revenue-analytics/index.tsx (marketing landing page) and src/hooks/productData/revenue_analytics.tsx. Removed the corresponding entries from useProducts, the analytics category in productNavigation.ts, hero carousel slots and analyticsHandles, Home/Board, Home/Control, Home/Test/Demos, and ProductsTest.
• Removed the <Link to="/revenue-analytics"> cell from src/hooks/competitorData/posthog.tsx (was rendered as the monetization_analytics value in product comparisons).
• Dropped the Revenue Analytics topic mapping from Questions/TopicsTable.
• Removed the revenue_analytics slides from product-managers.json / product-directors.json presentations.
• Removed revenue-analytics from src/lib/productInterest.ts and the "Revenue Analytics is included with Data Warehouse" pricing note in gatsby/rawMarkdownUtils.ts.

Removed from internal handbook playbooks

• which-products.md, use-case-selling.md, data-infrastructure.md, growth-and-marketing.md, product-intelligence.md, grow-an-account.md, product-enablement.md, utilization-by-business-type.md, why-buy-posthog.md, cross-sell-motions.md, error-tracking-cross-sell.md, onboarding-docs.mdx, teams/blitzscale/objectives.mdx.

Other docs cleanup

• data-warehouse/start-here.mdx: removed the Revenue analytics section in "Unify customer data".
• new-to-posthog/revenue.mdx: removed the "Revenue analytics dashboard" section and the cross-link to /docs/revenue-analytics from the data-warehouse paragraph.
• posthog-ai/example-prompts.mdx: removed the Revenue analytics prompt section.
• posthog-ai/tools.mdx: removed the filter_revenue_analytics tool row.
• settings/access-control.mdx: removed Revenue analytics from the supported-resources list.

Internal link suggestions

• Removed 21 Revenue Analytics rows from .claude/skills/InternalLinkData.csv.

Redirects

• Added /revenue-analytics → /docs/revenue-analytics in vercel.json so the deleted marketing page (and any external inbound links to it, like the exa.md customer quote) keeps working.

Kept intentionally

• Blog posts referencing Revenue Analytics (per the task brief).
• The docs themselves (contents/docs/revenue-analytics/*) and their nav sidebar in src/navs/index.js, so users actively on the product can still read setup/troubleshooting docs until removal.
• The revenueAnalyticsFeatures definition and the revenue_analytics rows in competitor data files — they're still wired through ProductComparisonTable, which contents/blog/posthog-vs-amplitude.mdx references directly.
• useFeatureOwnership mapping (team ownership label, not a customer-facing link).
• Vale linting exceptions for "Revenue Analytics" capitalization (docs still reference it).

Test plan

• Build the site locally (pnpm start) and confirm:
  • /revenue-analytics redirects to /docs/revenue-analytics
  • /docs/revenue-analytics and every child page show the deprecation banner
  • Home page, hero carousel, and product menus no longer surface Revenue analytics
  • contents/blog/posthog-vs-amplitude.mdx still renders the Revenue analytics comparison row
• pnpm test-redirects passes
• pnpm check-links-post-build does not flag broken /revenue-analytics outbound links
