Admin interface should display Minor Trace Chemistry data

[kbighorse]

Summary

Add a read-only admin interface for the legacy NMA_MinorTraceChemistry table in starlette-admin.

Background

The Minor and Trace Chemistry data is legacy data imported from the AMPAPI system. It contains analytical results for various chemical elements and compounds, linked to ChemistrySampleInfo records.

Implementation

• Read-only view: Create, edit, and delete operations are disabled since this is legacy data
• Parent association: Uses HasOne field to link to the parent ChemistrySampleInfo record
• List view: Shows key columns (GlobalID, Chemistry Sample Info, Analyte, Sample Value, Units, Symbol, Analysis Date, Agency)
• Search: Searchable by analyte, symbol, analysis method, notes, and agency
• Pagination: 50 records per page with options for 25, 50, 100, 200

Files Changed

• admin/views/minor_trace_chemistry.py - New admin view class
• admin/views/__init__.py - Export MinorTraceChemistryAdmin
• admin/config.py - Register view with admin
• features/admin/minor_trace_chemistry_admin.feature - BDD feature file
• tests/test_admin_minor_trace_chemistry.py - Unit tests (14 tests)

Testing

• All 14 unit tests pass
• Tests verify: registration, read-only restrictions, list/form field configuration, labels
