Summary

Migrate Apps / app detail AppContext consumers to exact bootstrap atom reads as the next domain migration after Datasets.

This PR replaces broad useAppContext() / useSelector() reads across app detail, app creation/import, app configuration, access control, and apps list/card surfaces with direct reads from app-context-state atoms such as userProfileIdAtom, workspacePermissionKeysAtom, currentWorkspaceAtom, and langGeniusVersionInfoAtom.

It also adds a shared atom mock helper for focused frontend tests and updates affected specs to mock the exact bootstrap atoms consumed by migrated components.

Checklist

• This change requires a documentation update, included: Dify Document
• I understand that this PR may be closed in case there was no previous discussion or issues. (This doesn't apply to typos!)
• I've added a test for each change that was introduced, and I tried as much as possible to make a single atomic change.
• I've updated the documentation accordingly.
• I ran make lint && make type-check (backend) and cd web && pnpm exec vp staged (frontend) to appease the lint gods

Validation:

• pnpm -C web test app/components/app/access-config/__tests__/index.spec.tsx 'app/(commonLayout)/app/(appDetailLayout)/[appId]/overview/__tests__/view.spec.tsx' 'app/(commonLayout)/app/(appDetailLayout)/[appId]/overview/__tests__/chart-view.spec.tsx' 'app/(commonLayout)/app/(appDetailLayout)/[appId]/overview/tracing/__tests__/panel.spec.tsx' 'app/(commonLayout)/app/(appDetailLayout)/[appId]/__tests__/layout-main.spec.tsx' app/components/app/create-from-dsl-modal/__tests__/index.spec.tsx app/components/app/overview/embedded/__tests__/index.spec.tsx app/components/app/log/__tests__/list.spec.tsx app/components/app/overview/__tests__/trigger-card.spec.tsx app/components/app/create-app-modal/__tests__/index.spec.tsx app/components/app/create-app-dialog/app-list/__tests__/index.spec.tsx app/components/app/app-access-control/__tests__/add-member-or-group-pop.spec.tsx app/components/app/configuration/debug/debug-with-single-model/__tests__/index.spec.tsx app/components/app/configuration/debug/debug-with-multiple-model/__tests__/chat-item.spec.tsx app/components/app/configuration/hooks/__tests__/use-configuration.spec.tsx app/components/app/configuration/dataset-config/__tests__/index.spec.tsx app/components/app/configuration/dataset-config/select-dataset/__tests__/index.spec.tsx app/components/apps/__tests__/app-card.spec.tsx app/components/apps/__tests__/list.spec.tsx app/components/apps/__tests__/index.spec.tsx app/components/apps/__tests__/creators-filter.spec.tsx --run
• git diff --check HEAD~1..HEAD
• pnpm --dir web exec eslint __tests__/utils/mock-app-context-state.ts --fix --cache --quiet

Notes:

• pnpm --dir web exec vp staged is currently blocked because this checkout's vite.config.ts does not define a staged config.
• pnpm -C web type-check is currently blocked by existing generated .next/types/validator.ts route/layout type errors unrelated to this PR's touched files.
• Running ESLint directly on all touched source files surfaces existing legacy rule violations in those files, including deprecated base Input imports, existing any usage, and existing a11y issues. This PR intentionally avoids expanding the migration into unrelated cleanup.
