ZCU-PUB/Enable per-bitstream embargo badge (item.bitstream.showAccessStatuses) (#1403)

* ZCU-PUB/Enable per-bitstream embargo badge (item.bitstream.showAccessStatuses)

The embargo-date badge (dspace-customers#823, FE #1378/#1390) is gated behind
item.bitstream.showAccessStatuses, which defaults to false in
default-app-config.ts. Set it to true in config.yml so the badge renders on
redeploy. Safe now that the backend accessStatus endpoint is deployed for
zcu-pub (DSpace#1377); the frontend fails closed without it.
