feat(hifsa): add 3D assignment viewer and public HiFSA panels

[vcnainala]

Summary

• Parse Cosmic Truth spinsystems.sdf and OUTPUT.json atom maps into study hifsa_data, and hide sentinel shift/coupling values.
• Add a 3Dmol.js assignment viewer and shared HifsaPanel on upload, dashboard datasets, and public study/sample/dataset pages.
• Pass an NMRium fileFilter that excludes EXTRA/ and hifsa/ paths so Cosmic Truth artifacts are not loaded as spectra.

This app does not use Filament. Backend helpers follow Laravel 13 conventions (typed support classes, API resource when(), eager-loaded sample.molecules for the datasets view).

Test plan

• Open a HiFSA study in upload and confirm the HiFSA panel shows scores plus shift/coupling overlays on the CT structure.
• Confirm public study, sample, and dataset pages render the same panel when hifsa_data is present, and hide it when absent.
• Load a HiFSA sample in NMRium and confirm EXTRA/hifsa files are not imported as spectra.
• php artisan test --filter='HifsaAtomLabelsTest|HifsaNmriumFileFilterTest|DraftHifsaPdfTest|PublicHifsaViewTest'
