Matt Johnson 966661305f feat(gui): generic adapter edit form 
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.
