/**
 * Backfill auth.users.app_metadata.has_password for the BankID-MFA lockout fix.
 *
 *   - BankID-linked users (app_metadata.bankid_linked === true) with the flag
 *     unset → set has_password = false. Banner in SecuritySettings will then
 *     guide them through /account/set-password before MFA enroll is unlocked.
 *
 *   - All other users with the flag unset (legacy email/password signups) →
 *     set has_password = true. They have a real password.
 *
 *   - Anyone with the flag already set is left alone — fully idempotent.
 *
 * Usage:
 *   npx tsx scripts/backfill-has-password.ts            # apply
 *   npx tsx scripts/backfill-has-password.ts --dry-run  # report only
