Remove treeshake:false, delete dead GraphQL ops, fix broken section-move route

[nbudin]

Purpose

A few things bundled together because they were all found during the same investigation.

treeshake: false removed. This workaround was added for a Rolldown bug with GraphQL document constants being silently eliminated. Turns out the bug no longer exists. Verified by writing scripts/check-graphql-documents.mts, which collects all operation names from the source .generated.ts files and confirms they survive the build — same 502 operations pass whether treeshaking is on or off.

8 dead GraphQL operations deleted. Found them as a byproduct of the check: AdminStoreAbilityQuery, MailingListsMenuQuery, WhosFreeFormConventionQuery, and five Standalone* mutations in StandaloneEditEvent. None of their document constants were imported anywhere. Source .graphql files and generated .ts files cleaned up via codegen.

Broken section drag-and-drop fixed. While checking MoveFormSection (also absent from the build), noticed that the route action file existed and was correctly implemented, but the route itself was never registered in AppRouter.tsx. The UI was submitting to /admin_forms/:id/edit/section/:sectionId/move and silently failing. One missing route entry, now fixed.

GraphiQL imports consolidated. CmsGraphqlQueryForm previously had a static import of @graphiql/toolkit alongside its lazy import of graphiql. Both now live in GraphiQLWithFetcher.tsx, lazily loaded as a unit.

Changes

💻 Engineer-facing

• yarn check-graphql-documents — run after yarn build:web to verify all expected operations are in the output. Fails with a list of anything missing.
• CI job in static.yml runs the build + check on every PR
• KNOWN_ABSENT in the script is currently empty — if you add an operation that's intentionally unreachable, add it there

🚢
