/**
* Contract template separation — schema introduction (Phase 2)
*
* Creates dedicated tables for contract templates and establishes helper views
* to compare legacy template rows (previously stored in `contracts`/`contract_lines`)
* with the new structure. After this phase, `contracts` focuses on client-specific
* agreements while `contract_templates` owns reusable blueprints. Foreign keys are
* created as NOT VALID so we can backfill data before enforcing referential integrity
* during the cutover window.
*
* @param { import('knex').Knex } knex
* @returns { Promise<void> }
