fix(web): keep layout-leaf style-editor columns distinct from name collisions

columnsFor() keyed a layout-only leaf field's column by its bare field
name. If an unrelated element's style block or another element's layout
axis block happened to declare a sub-field with that same name, the
`!seen.has(key)` guard skipped creating the leaf's column, silently
dropping its only control again -- the same failure the leaf-column fix
was meant to close, just reached through a name collision (CodeRabbit
review on 324a7ea).

Key layout-leaf columns under a namespaced id so they can never be
shadowed by an unrelated column sharing their name.
