feat: testing suite and bug fixes (Fasa 11)

- AuthTest, ProgramTest, CheckinTest, QuestionnaireTest, CertificateTest — 19 feature tests, 35 total pass
- ProgramFactory with published() state
- UserFactory: is_admin=true default, nonAdmin() state
- Fix attendance_source column name in StatisticsController (was: source)
- Fix route(dashboard) → route(admin.dashboard) in all Breeze auth controllers
- Remove irrelevant Breeze boilerplate tests (Profile, Example, Registration)
