docs(skills): drop the five GraphQL residue sites and the stale /storage mount

`/graphql` is not mounted: `packages/runtime/src/http-dispatcher.ts:2069` is
`// /graphql removed — GraphQL is not in the product plan (#2462 follow-on)`,
there is no `createGraphQLDomain` among the registered domains (0 hits under
`packages/*/src`), and `handleGraphQL` survives only in CHANGELOGs. Five sites
in the published catalog still described it as a live ObjectStack surface —
the input that generates client code against a route which 404s.

- `objectstack-api` tags: drop `graphql` (the description one line above
  already lists no GraphQL surface).
- `objectstack-data` `apiEnabled`: REST + MCP, the two surfaces the flag
  actually gates (`packages/mcp/src/stdio-data-bridge.ts:260` reads
  `enable.apiEnabled === false`).
- `objectstack-platform` mount line: `createHonoApp` mounts auth and
  discovery only. `/storage` was stale on the same line and is corrected in
  the same edit — `packages/adapters/hono/src/index.ts:423` is
  `// --- Storage: deliberately NOT mounted (#4087) ---`, and the dispatcher
  carries the matching "No `/storage` domain (#4087)" note.
- `objectstack-formula`: the `GraphQL.ComputedField` CEL-host row and the
  `api/graphql` cache-key row are deleted rather than replaced — no real
  surface fills either slot (the computed-field CEL host is already the
  `Field` / `type: 'formula'` row above it, and no cache-key template surface
  exists: `system/cache` takes plain key patterns, `api/http-cache` has none).

The mirror row in `content/docs/ai/skills-reference.mdx` moves in this same
commit, per the card's anti-drift requirement — never before or after the
skill it catalogs.

Bundle effect: -27 tokens on the published skills ratchet.

Fixes #10846

CEL expressions in route guards or auth predicates: load objectstack-formula alongside.
