Remove duplicate/unused golden files

Removed old golden files from earlier test iterations:
- drink_detail_beer_*.png
- drink_detail_cider_*.png
- drink_detail_rated_*.png
- drink_detail_tablet_*.png
- brewery_screen_location_*.png
- brewery_screen_phone_*.png
- brewery_screen_tablet_*.png

These were from test cases that were removed/simplified to avoid layout overflow issues.

Now have exactly 22 golden files (11 tests × 2 themes) matching the current test suite.
All screenshot tests pass ✅
