Implement Central 2-A2: generic adapter edit form feature.
- Add form_descriptors.py with describe_fields() and FieldDescriptor
- Maps Pydantic types to HTML widgets (text, number, checkbox, csv, region)
- Handles Optional types by recursively resolving inner type
- Uses PydanticUndefined handling for proper default values
- Update routes.py GET/POST handlers:
- Use cached _adapter_classes() for adapter class lookup
- Generate field descriptors from adapter settings_schema
- Parse form values based on widget type in POST handler
- Validate settings via Pydantic ValidationError
- Update adapters_edit.html template:
- Render form dynamically from field descriptors
- Support all widget types (text, number, checkbox, csv, region)
- Use adapter.display_name and adapter.description from class
- Delete per-adapter templates:
- adapters_edit_nws.html
- adapters_edit_firms.html
- adapters_edit_usgs_quake.html
- Add tests/test_form_descriptors.py with comprehensive coverage
- Update tests/test_adapters.py to include last_error in mock rows
- Update tests/test_region_picker.py to include last_error in mock rows
Adding a new adapter no longer requires GUI template work.
