feat(cashier, sponsor-dd): GL settlement and DD funding entry points, DD registry redesign

Transaction Entry (clerk):
- Route a two-row Fund Transfer of Dr SHR / Cr GL to the share-withdrawal
  request with settlementMode GL, so a clerk can settle a share withdrawal
  into any GL account instead of the member's linked savings account.
- Offer GL as an account type for Demand Draft funding, and submit it as a
  GL debit (no client or savings/current account is involved).

My Work:
- Add a voucher detail dialog so a clerk can open a raised voucher from the
  request list and see its GL lines.

Closing Cash Report:
- Fix the total row so it reflects the corrected opening balance.

DD Leaflet Registry and DD Inventory:
- Redesign both pages onto the shared usr-* visual language: gradient header
  badge, status filter chips with counts, card-wrapped sticky-header table,
  and one primary action per row with the rest behind an overflow menu.
  Filtering, pagination and every action condition are unchanged.
- Register faHandPaper, needed by the new Stop Payment menu item.
