Merge branch 'dev' into feature/bugfix

Conflicts resolved in:
- src/app/clients/clients-view/ckyc-tab/ckyc-tab.component.html
- src/app/clients/clients-view/ckyc-tab/ckyc-tab.component.ts

Kept dev's CKYC architecture (upload dialog, real per-artefact endpoints)
and layered feature/bugfix's fixes on top: upload file validation,
missing-file badge, silent preview download, and image/PDF view button.
Also includes the CKYC "Image of Client" upload-state fix and the
client-change state-leak fix in the same component.
