fix(dbal): add tenantId auto-add to loadFromDirectory, fix ComponentNode schema

loadFromDirectory() was missing the tenantId field auto-add logic that
loadFromFile() already had, causing "Unknown field: tenantId" on all
entities using the shorthand `"tenantId": true` convention.

Also corrected ComponentNode schema to match the C++ struct fields
(pageId, parentId, childIds, order) instead of the wrong Redux shape.
