/**
 * E2E — Phase 5 / Task C2: kitchen-sink regression for the secrets allowlist.
 *
 * Seeds a source app with ONE row in every secret-leakable column from the
 * spec's allowlist, clones it, and asserts:
 *   ✓ non-secret fields copied (oauth provider/URL, function code, _seed rows)
 *   ✓ secret fields are NULL on dest (oauth client_id/secret, encrypted_env_vars,
 *     ai_config.byokKey)
 *   ✓ whole-table "not-copied" categories are absent on dest (app_users,
 *     app_refresh_tokens, app_verification_codes, app_integration_configs,
 *     app_connected_accounts, function_invocations, storage non-_repo objects,
 *     app_signing_keys)
 *   ✓ _seed table rows travel; non-_seed user-data rows do NOT travel
 *
 * TABLE / CATEGORY COVERAGE (see helpers/kitchen-sink.ts for full audit):
 *
 *   VERIFIED (seeded + asserted in this test):
 *     app_oauth_configs          client_id + client_secret_encrypted BLANKED
 *     app_functions              encrypted_env_vars BLANKED
 *     apps.ai_config             byokKey BLANKED
 *     app_users                  NOT COPIED
 *     app_refresh_tokens         NOT COPIED
 *     app_verification_codes     NOT COPIED
 *     app_integration_configs    NOT COPIED
 *     app_connected_accounts     NOT COPIED
 *     function_invocations       NOT COPIED
 *     storage_objects (non-_repo key) NOT COPIED
 *     app_signing_keys           NOT COPIED
 *     _seed table (countries)    COPIED
 *     non-_seed table (private_records) NOT COPIED
 *
 *   N/A — not in this codebase:
 *     custom_domains             No CREATE TABLE found in runtime/control schemas
 *
 *   N/A — no app_id column, platform-level table:
 *     api_keys                   control-plane only (keyed by user_id); never per-app
 *
 * Drives control-api at http://localhost:4000.
