🧪 test: reduce BDD undefined steps from 52 to 1

- Add missing JWT secret rotation step definitions

- Implement JWT retention policy step implementations

- Fix step pattern matching for Godog compatibility

- Add proper godog.ErrPending for unimplemented steps

- Resolve argument mismatch in step definitions

Reduces undefined steps by 98% (52 → 1)

All JWT secret rotation scenarios now have step definitions

Remaining undefined step is response validation pattern issue
