feat(onboarding/phase-6): setup wizard polish, seed script alignment, doctor visit slots

- Setup wizard: 3-pane layout with right-side live previews, resume
  banner, edit/copy icons on team step, AI prompt configuration
- Forms: employee-create replaces invite-member (no email invites),
  clinic form with address/hours/payment, doctor form with visit slots
- Seed script: aligned to current SDK schema — doctors created as
  workspace members (HelixEngage Manager role), visitingHours replaced
  by doctorVisitSlot entity, clinics seeded, portalUserId linked
  dynamically, SUB/ORIGIN/GQL configurable via env vars
- Pages: clinics + doctors CRUD updated for new schema, team settings
  with temp password + role assignment
- New components: time-picker, day-selector, wizard-right-panes,
  wizard-layout-context, resume-setup-banner
- Removed: invite-member-form (replaced by employee-create-form per
  no-email-invites rule)
