docs(admin): add captured screenshots for admin menu bundle (PR H)

Captures all 3 planned screenshots × 4 languages (12 PNGs):
- resource_policy_list_csv.png — Keypair Resource Policy table with Export CSV menu at BAITable bottom-right (FR-2824)
- container_registry_editor_modal.png — Add Registry modal with new SSL Verification checkbox (FR-621)
- model_card_delete_with_folder.png — Delete Model Card dialog with "Also delete the associated model folder" option and cascade warning (FR-2622 family)

Captured at 2× zoom via Portless dev, per-locale via window.switchLanguage(). Test resources (demo-model-folder, demo-model-card) were created and fully cleaned up via the captured delete flow itself.

 To save the current resource policy list as a CSV file, use the **Export CSV** action in the **bottom-right slot of the table**. This applies to the Keypair, User, and Project resource policy tabs alike — the CSV export control has been moved from the header area to the table's bottom-right toolbar for consistency with other admin lists.

Disable this only for a registry served with a self-signed certificate inside a trusted internal environment where you have already verified the network path; turning it off makes the connection vulnerable to man-in-the-middle attacks.
