Creates template_trees and platform_steps (no account_id, no RLS). Migrates is_default=TRUE trees and public steps into them. Creates sentinel platform account (00000000-...-0001) for global tree_categories, tree_tags, step_categories, step_library, and is_default trees — clearing all NULL account_id rows in those tables as prerequisite for Group 9 SET NOT NULL.
