Re-shoot manual screenshots showing Barclays as Acme Corporation

Five manual chapters carry real UI screenshots captured against the barclays_plc tenant, back when Barclays Plc was the system's reference/demo entity: chapter_tenants.org (Tenants window, showing the barclays_plc tenant row), chapter_accounts_and_roles.org (New Account — Parties tab, assigning to BARCLAYS PLC), chapter_connecting.org (logging in as tenant_admin@barclays_plc), chapter_parties.org (Party History dialog for BARCLAYS BANK PLC), and chapter_counterparties.org (prose mentioning "Barclays' counterparties"). Now that Acme Corporation is the system's reference entity (see the story below), re-shoot each of these against a freshly provisioned Acme Corporation tenant, following How do I capture screenshots for a manual chapter?, and update each caption/prose reference to match the new image (e.g. acme_corporation tenant code, tenant_admin@acme_corporation, an Acme legal entity in place of BARCLAYS PLC=/=BARCLAYS BANK PLC).

The Write user manual chapter: Acme Corporation as the system's test/demo entity task deliberately left these five chapters untouched — their screenshots are real UI captures, so editing the prose without re-shooting the image would leave a caption describing something the picture doesn't show. This capture is that deferred re-shoot, so the whole manual is consistent about which entity is the system's reference/demo tenant.
