UI: multi-panel rendering, SVG grouping, and pipeline format support

[ThomasHMAC]

• Closes Address UI requirements #4

Summary

Implements a modular UI panel system and QC task rendering logic for QC-Studio.

Features

• UI Panels

  • NiiVue (3D viewer with overlays + FreeSurfer mesh support)
  • SVG montages (single/multiple, tabbed by session/task/run)
  • Optional IQM distributions (gracefully skipped if absent)

• Flexible Rendering

  • Multiple SVG montages per task
  • Single panel rendering (NiiVue / SVG / IQM)
  • Combined panels (e.g., NiiVue + SVG)
  • Multiple QC tasks as tabs

• BIDS Grouping

  • Automatic grouping by session/task/run from filenames
  • QC rating UI mirrors grouping (one rating per group)

Pipeline Support (NiiVue)

• fMRIPrep: .nii.gz BOLD/T1w + masks
• FreeSurfer: .mgz + surface meshes
• QSIPrep: basic .nii.gz support (further validation ongoing)

Notes

• Focused on flexible UI architecture
• IQM distributions are pipeline-agnostic
• QSIPrep support will be expanded in follow-up work
