Summary

Migrate account settings, account dropdown/header, and delete-account AppContext consumers to direct bootstrap atom reads.

This keeps the existing compatibility provider in place while narrowing subscriptions to exact account, workspace, permission, role, version, and refresh atoms at each use site. It also updates related tests to mock the precise app-context-state atoms used by the 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 exec eslint --fix --cache --quiet <changed TS/TSX files>
• pnpm -C web type-check
• pnpm -C web test app/components/header/account-dropdown/__tests__/index.spec.tsx app/components/header/env-nav/__tests__/index.spec.tsx app/components/header/account-setting/__tests__/index.spec.tsx app/components/header/account-setting/members-page/__tests__/index.spec.tsx app/components/header/account-setting/members-page/__tests__/invite-button.spec.tsx app/components/header/account-setting/members-page/edit-workspace-modal/__tests__/index.spec.tsx app/components/header/account-setting/members-page/edit-workspace-modal/__tests__/dialog.spec.tsx app/components/header/account-setting/members-page/transfer-ownership-modal/__tests__/index.spec.tsx app/components/header/account-setting/permissions-page/__tests__/index.spec.tsx app/components/header/account-setting/permissions-page/role-list/__tests__/row-menu.spec.tsx app/components/header/account-setting/api-based-extension-page/__tests__/index.spec.tsx app/components/header/account-setting/access-rules-page/__tests__/access-rule-section.spec.tsx app/components/header/account-setting/model-provider-page/system-model-selector/__tests__/index.spec.tsx app/components/header/account-setting/model-provider-page/provider-added-card/__tests__/index.spec.tsx app/components/header/account-setting/model-provider-page/provider-added-card/__tests__/model-list.spec.tsx app/components/header/account-setting/model-provider-page/provider-added-card/__tests__/model-list-item.spec.tsx app/components/header/account-setting/preference-page/__tests__/index.spec.tsx

Note: pnpm -C web exec vp staged currently exits before checks with No "staged" config found in vite.config.ts, so I ran the equivalent explicit frontend checks above.
