The Accounts grid duplicated the sidebar account list. Removing it gives
the Goals section more breathing room and the page a tighter narrative:
header → KPIs → Goals.
Delete Savings::AccountCardComponent, Family#savings_subtype_accounts,
the @savings_accounts / @account_goal_counts controller refs, and the
related locale keys. Sidebar still shows the savings-subtype Depository
accounts under "Cash" — no information is lost.
