fix(turbo-boundaries): resolve 32 violations

- Re-tag core-trpc as core-composition (transitively reaches features
  through core-api's AppRouter type) and allow core-composition packages
  to depend on other core-composition packages in turbo.json
- Add @payloadcms/richtext-lexical as direct dep of apps/cms (was pulled
  transitively via core-cms; Payload's importMap.js imports it directly)
- Add @storybook/react as devDep of core-ui and apps/storybook (stories
  belong with components per Atomic Design)
- Update apps/storybook .storybook/{main,preview}.ts to point at
  packages/core-ui (was still referencing deleted packages/ui) and export
  CSS via package exports instead of direct file import
- Add JSDoc type annotation to Payload-generated importMap.js to suppress
  TypeScript's TS2742 error from complex inferred types
- Add storybook-static to eslint ignores in core-eslint base config

pnpm turbo boundaries now reports zero violations.
