Upgrade to OHIF 3.13.2 and UI version

[erinaldidb]

Summary

Upgrades the bundled OHIF viewer from 3.12.10 to 3.13.2 and bumps the Pixels UI_VERSION from 1.3.0 to 1.4.0 so existing deployments can detect that a newer viewer build is available.

The change is almost entirely the OHIF static build under apps/dicom-web/ohif/ (hashed JS/CSS/WASM bundles, service worker, index.html). It also ships the 3.13 URL-customization catalog (customizations/*.jsonc) that OHIF now includes for segmentation tools, CT presets, measurement labels, and worklist overlays.

Viewer-facing 3.13 capabilities that come with this bump (OHIF v3.13 release notes):

• Smart scrollbar with load-progress for large series
• New study list (WorkListUINext)
• UI-next component library and appearance/theming
• Labelmap / one-click segmentation improvements (ClickSegmentTool)
• Cornerstone3D v5 viewport stack (including DICOM video via the Cornerstone viewport)

UI_VERSION is what the viewer config page compares against main to show the “newer UI available” banner (src/dbx/pixels/common/pages.py).

Test plan

• Rebuild/deploy the viewer (make build so dist/ohif.tar.gz matches this OHIF tree; then bundle deploy / install job deploy_prep + deploy_viewer)
• Open the OHIF viewer with a test study (MONAI Label mode) and confirm studies, series, and frames render
• Confirm QIDO/WADO still work through the viewer → gateway OBO chain
• Exercise segmentation tools (brush / one-click / labelmap) and save if used in this environment
• Confirm the config landing page shows UI version 1.4.0
• Smoke-test the new study list / scrollbar behavior on a multi-slice CT
