* feat(gui): add Leaflet region picker to adapter edit (1b-5)
- Add _region_picker.html template with Leaflet map and editable rectangle
- Add Leaflet 1.9.4 and Leaflet.draw 1.0.4 CDN deps to adapters_edit.html
- Update GET /adapters/{name} to fetch map_tile_url from config.system
- Update POST /adapters/{name} to validate and save region coordinates
- Validation: -90 <= south < north <= 90, -180 <= west < east <= 180
- Region changes flow through to audit log via existing settings capture

* fix(tests): update adapter tests for region picker mocks
Add region coordinates to form data mocks and system settings rows
to fetchrow.side_effect for tests that re-render on validation errors.
