feat(shares): dynamic Share Reports module, voucher attach/GL sync fixes

- Add the full Share Reports surface (final balance, account statement,
  issued/status/nominal/share-wise/guarantor/member-interest reports, enquiry,
  payment certificate, share detail, dividend statement, folio statement,
  distinctive numbers, area-wise, mailing labels/letters, share transfer) as
  standalone routed components, wired into the Share menu
- Wire the unattributed Share Collection receipt list into Apply Collection
  and Apply Additional Shares, with an Attach action independent of
  account/client
- Sync the GL Account and Voucher No fields to whichever receipt is ticked or
  found, and surface the receipt's real Dr/Cr GL entries in its detail popup
- Block Apply Additional Shares until the account's original application is
  settled
