Load inline editing based on seed flag

Replace URL-based editMode detection for inline editing loading
with a loadInlineEditing flag in the seed config. The server
sets the flag, the jbuilder template renders it and derives
translation inclusion from it. This prepares for other features
using the same pattern to control client-side loading.
