fix(review): address 2026-06-08 review report issues

## Fixed

### High-4: CI 与质量门禁不一致
- Add quality-gates job that runs verify_quality_gates.sh
- Fix Docker job: correct binary paths and remove || true
- Replace fake version/help checks with real health endpoint probe

### High-5: 敏感信息持久化到 localStorage
- Add SENSITIVE_FIELDS list to admin-common.js (adminToken, token, password, key, apiKey, etc.)
- writeStoredConfig now filters sensitive fields by default
- Add allowSensitive option for explicit opt-in (default false)
- Add createSensitiveStorageToggle() UI helper with warning banner
- Update admin/index.html placeholder text to remove misleading 不落盘 claim

### Medium-4: JSON 解码错误静默
- Fix scanUserKeys: return error when allowed_models JSON decode fails
- Fix scanOneUserKey: return error when allowed_models JSON decode fails
- Prevents silent data corruption that would show empty model list

## Quality Gates
✅ go build ./... - PASS
✅ go test ./internal/... - PASS (all packages)
✅ bash ./scripts/test/verify_quality_gates.sh - PASS

## Notes
- High-6 (凭证可预测) requires architecture change to store random credentials in DB
- Medium-3 (部署脚本默认值) considered lower priority for current scope
