feat(shares, cashier): Entry Type tagging on Transaction Entry, real GL details on receipts

Adds an Entry Type field to Transaction Entry's GL-crediting rows (Receipt / Collection),
fetched from the backend's GLEntryType code, so the counter can flag what a GL credit is
actually for (General / Share Collection / DD Issue) instead of leaving every GL account
picker throughout Share Advance Collection guessing from the whole chart of accounts.

Apply Share / Additional Share screens:
- GL Account picker narrowed to accounts that actually have an eligible receipt, and only
  auto-selected when exactly one candidate exists -- no more defaulting to whichever account
  sorts first (Cash at Vault).
- Voucher tables show Description and Collected By, and a Detail view exposes the receipt's
  real Dr/Cr GL legs instead of the GL Account dropdown's current unrelated selection.
- Additional Share funds from a single voucher (radio-style selection); ticking a receipt
  syncs the GL Account picker to its own actual account.
- Checker's Additional Share Request review dialog gets the same Description + real GL entry
  detail, expandable per voucher, so approval is never a guess about what will post.
