refactor: remove verified dead code — orphan file, dead HOC, unused api wrappers

From the repo-wide dead-code audit (High-confidence, re-verified against the live
tree; 0 references each):
- Delete client/components/SummaryCard.tsx — orphan superseded by the tracker's
  components/tracker/SummaryCards.tsx (the one actually imported).
- Remove the unused withErrorBoundary HOC from ErrorBoundary.tsx (the
  ErrorBoundary component itself stays; it's used app-wide).
- Remove 17 dead api.ts client wrappers with no caller (spendingBudgets,
  upcomingBills, billAmortization, billMonthlyState, archiveBill,
  deleteBillTemplate, updateSnowballPlan, aboutAdmin, exportUrl, notifMe,
  saveNotifMe, profileExports, profileImportHistory, createManualTransaction,
  updateTransaction, deleteTransaction, transactionMerchantMatch).

Deliberately left: StatusBadge.tsx orphan (has uncommitted parallel edits — will
remove once that lands) and the WebAuthn feature (a build-or-bin product decision,
not dead-code cleanup).
