fix(editor): respect no-login settings visibility in config navigation (#6807)

# Description of Changes

This change fixes the editor configuration navigation for issue #6800 by
passing the `showSettingsWhenNoLogin` configuration flag through all
config navigation section hooks.

- Added `config?.showSettingsWhenNoLogin ?? true` when building the app
config modal navigation.
- Extended shared, desktop, and proprietary `useConfigNavSections`
signatures to accept the `showSettingsWhenNoLogin` flag.
- Forwarded the flag from desktop and proprietary config navigation
wrappers into the shared navigation logic.
- Updated proprietary admin section visibility so read-only admin
previews are only shown when login is disabled and
`system.showSettingsWhenNoLogin` allows it.

The change was made to ensure deployments with login disabled can still
control whether settings/admin configuration entries are visible,
matching the existing `showSettingsWhenNoLogin` behavior.

Closes #6800
