fix: remove home app from Wagtail template to resolve InvalidBasesError

The home app (HomePage extending wagtail.models.Page) caused a Django
InvalidBasesError during migrate because the home app used syncdb while
wagtailcore participates in the migration framework. Removing the app
avoids the conflict; the initial Wagtail root/home pages are now created
using plain Page instances. The base Django HomeView is unaffected.
