ht 7ec6febf23 fix: 修复销售价格校验崩溃与备份日志无效外键 ... 1) SaleItemForm.clean 中 product.price * 0.5 是 Decimal * float，会抛 TypeError，导致添加/编辑销售单商品时崩溃。改用 Decimal('0.5')/Decimal('2')。 2) 备份/恢复写 LogEntry 时用 content_type_id=0，0 号 ContentType 不存在， 违反外键约束抛 IntegrityError；且该调用在 try 内，失败会连带删掉刚生成的 备份目录。改为 content_type_id=None（该字段可空）。 Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>		2026-05-28 23:40:35 +08:00
