refactor(题单后台): 添加 / 编辑弹窗两两合并成 ProblemModal、BadgeModal

AddBadgeModal / EditBadgeModal、AddProblemModal / EditProblemModal 各是两份八成相同
的组件，改一处表单项另一处总要漏。合并成一个组件，传了 badge / problem 就是编辑、
null 就是添加；两种模式分别 emit create / update，detail.vue 的四个 handler 不变。

表单项、校验、文案、提交的数据形状都照旧（题目弹窗添加时带 problemId、编辑时只显示
标题）。有一处刻意的行为变化：编辑弹窗原来只在换了一条记录时才重新填表，取消后再打开
同一条会看到上次没保存的改动；现在每次打开都按库里的值重新填。
