Drop company_id column from all 22 domain tables via migration.
Remove companyId from JWT payload, auth plugins, all service method
signatures (~215 occurrences), all route handlers (~105 occurrences),
test runner, test suites, and frontend auth store/types.

DB per customer) not the application level.
All 107 API tests pass. Zero TSC errors across all packages.
12 RBAC API tests: permission denial for no-role users, viewer read-only,
sales associate can create but not delete, technician scoped access,
instructor inventory denied, admin full access, permission inheritance
(admin implies edit+view), system role undeletable, custom role lifecycle.
