Remove orphaned pages and fix accidental context-warehouse routes

[ianmatson]

Removes dead routes identified by tracing the import graph and the internal link graph, then cross-checking against 90 days of pageviews. Every page removed here was at crawler-level traffic (8–29 views per quarter).

Deleted pages

Route	Views (90d)	Why
/questions/topic/max	8	Superseded by /questions/topic/ai
/event-comparison	9	No entry point anywhere
/community/latest	19	Not reachable from the community nav
/flurry-migration	13	Flurry shut down in 2025
/old-home	29	Previous homepage, kept after the rebuild

Redirects

From	To	Status
/questions/topic/max	/questions/topic/ai	301
/community/latest	/community	301
/old-home	/	301

Added at the top of the redirects array, since vercel.json matches top-down and takes the first hit.

/event-comparison and /flurry-migration get no redirect and will 404 — that was the call on the audit, since neither has a successor page.

Accidental routes

CDPDiagram.tsx, FeatureTable.tsx and dw-installation-platforms.tsx were React components living in src/pages/context-warehouse/, so Gatsby's file-system routing published each one as a public route.

• CDPDiagram had no importers → deleted.
• FeatureTable (used by business-intelligence and posthog-ai) and DWInstallationPlatforms (used by sources) → moved to src/components/ContextWarehouse/. Same components, no accidental pages.

Orphaned components

Deleting the pages above left two components with no importers, both now removed:

• components/ContactSales/Contact.tsx (391 lines) — a legacy formik + HubSpot contact form. ContactSales/index.tsx, which every live caller uses, renders SalesforceForm and never imported this file.
• components/Home/Index.tsx (23 lines) — a stub whose own copy read test. @todo i think this is old?.

The import graph was re-run afterwards; no further files were orphaned.

Also

Drops old-home and data-stack/dw-installation-platforms from the Algolia exclusion patterns in gatsby/algoliaConfig.js, since neither route exists now.

Notes for review

• /questions/topic/ai is worth a spot-check on preview. It resolves via the {SqueakTopic.slug} collection route and topicIcons carries a 'posthog ai' entry, so the topic node should exist — but the link is moderator-gated in useTopicsNav, so it only drew 2 views in 90 days and I could not confirm it renders without a build. /questions is the safe fallback if it 404s.
• /code/open was on the delete list but is left in place. It is not a content page: it reads ?to= and hands off to posthog-code:// to launch PostHog Desktop, which a redirect cannot replicate.
• components/CustomerLogos/LovableLogo.tsx is dead but was orphaned by Remove lovable from customer surfaces :( #19494, not by this PR, so it is left alone.
• No build was run.

Eager-graph budgets are report-only until a baseline is established. Sizes are gzip of public/**/*.js; eager size is webpack module source bytes for the modules actually shipped in the entrypoint's initial chunks (post-tree-shake).
