Lay the data foundation of the getting-started checklist, without UI:
- transactionService.getTransactionCount(): unfiltered COUNT(*) of transactions
- onboardingService: getOnboardingCounters() reads the five aggregated counts,
the import folder and the onboarding_checklist_hidden preference in one
Promise.all; hideChecklist()/showChecklist() persist the preference and log
- utils/onboardingChecklist.computeChecklist(): pure computation of the six
rows (profile, importFolder, source, import, manualCategory, budget), with
the budget row locked and excluded from the total when the edition has no
Budget
- hooks/useOnboardingChecklist: exported reducer + initial state, actions
refresh/hide/show, composed with useEntitlement("budget"); a load error
sets status "error" and keeps the hidden flag
- types OnboardingCounters, ChecklistItem, ChecklistItemKey
Tests cover every row in isolation, the budget gating (total 5 vs 6, complete
at 5/5 locked and 6/6 open), the aggregated query and preference reads, and
every reducer action. No DB migration, no CHANGELOG entry (centralised in #357).
