gsxdsm 5ff7a20738 FN-7976: fix mailbox artifact open and view-task popups

Fix Mailbox/Artifacts media auth and ensure View task always opens a usable popup.

- Add artifactMediaUrlWithToken for authenticated img/video/audio/link loads while keeping artifactMediaUrl token-free for fetch and HTML previews
- Load script-capable HTML artifact previews via Authorization + revocable blob URL so tokens never reach allow-scripts iframes
- Keep non-board/list task popups (Mailbox, Documents) visible even when board/list-only popup gating is enabled
- Upgrade duplicate popOut entries so reopening a task refreshes snapshot and origin
- Document the behavior and add a patch changeset
