chore(onboarding): delete the dead first-run components and their orphaned strings (#1488)

The activation analysis (2026-08-07) verified these have zero importers or
triggers; the new stepped checklist and its PostHog funnel replaced their
roles:

- SuccessAnimation (confetti variant): never mounted, and the completion
  moment is now the quiet check-morph signature, so it will stay unused
- AgentSetupBanner, ConsultantEmptyState: never mounted
- EmptyReceipts + its Camera import: only consumer of the preset_receipts_*
  strings and of a /receipts/scan route that does not exist
- new_user_checklist i18n namespace (24 keys x 2 locales): the old wizard
  copy; the live checklist reads initial_setup

The onboarding.empty agent intent stays: it is registered in the intent
table and reachable via /api/agent/invoke, so removing it is a product
decision, not dead-code removal.
