fix: address code review findings - crash fixes, proxy OCR accuracy, lint cleanup

- tools/proxy/server.js: add systemInstruction + temperature 0 (fixes brand name hallucination e.g. Tokai->Tokaisou)
- gemini_service.dart: add cache read/write to proxy path (was missing, cache was dead code in production)
- camera_screen.dart: guard cameras.first crash when no camera available, add mounted checks in gallery loop
- sake_detail_screen.dart: remove unused gemini_service import, add ignore comment for showDialog context lint
- sake_basic_info_section.dart: remove redundant null-assert operators flagged by dart analyze
- dev_menu_screen.dart: remove unused gemini_service import
- 6 service files: remove emoji from log strings (project rule compliance, 60+ instances)
