Add 5 new E2E tests for period logging modal and edit/delete flows

New tests cover:
- Period date modal opens from dashboard onboarding banner
- Period date input restricts future dates via max attribute
- Logging period from modal updates dashboard cycle info
- Edit period modal flow changes date successfully
- Delete period confirmation flow removes entry
