feat(shares): real-profit driven dividend UI, Dividend Dashboard, and member claim workflow

Frontend counterpart to the backend dividend rework:
- Create Dividend screen auto-computes the amount from real bank profit x officer
  percentage, blocks overlapping declaration periods, and adds a Total Dividend Paid
  summary card.
- View Dividend page modernized and reusable as an embedded popup from the new
  cross-product "Dividend Requests" approval-center tab.
- New consolidated Dividend Dashboard: summary stats, every declaration and its
  status, locked-dividend-vs-overdue-EMI matching with a proactive apply-to-loan
  action, full 3-year lock history, and a maker-checker claim panel letting a clerk
  split a member's unclaimed dividend across an overdue loan, savings credit, or
  cash for a manager to approve.
- Menu/routing consolidated under Share > Dividend Management; removed the
  now-unreachable Failed Dividend Payouts page and its home-dashboard alert once the
  backend stopped needing a retry path for stuck payouts.
