fix(exams): fix rich editor crashes and redesign form layout

Browse Source 
- Fix groupBlock/questionBlock insertContent error: empty content violates
  schema "block+", now provide default empty paragraph
- Fix buildTiptapDocFromAiResponse: ensure groupBlock/questionBlock always
  have content (fallback to empty paragraph)
- Add wrapInGroup/wrapInQuestion commands to wrap selected text into
  question/group blocks (vs insert which creates empty blocks)
- Update SelectionToolbar: use wrap when text selected, insert when not
- Redesign exam-rich-form layout:
  - Merge basic info into single-row toolbar (title/subject/grade/difficulty/score/duration)
  - Remove separate "source text" textarea (user pastes directly in editor)
  - AI auto-mark now reads from editor content via getText()
  - Editor + preview takes full height (calc(100vh-180px))
- Enhance AI prompt for Chinese exam papers:
  - Support reading material (阅读理解选段)
  - Support dotted chars (加点字注音)
  - Support sub-questions (阅读理解小题)
  - Better type detection (single/multiple choice, judgment, fill, essay, composite)
- Add splitByDottedTexts helper to mark dotted chars in Tiptap doc
- Add i18n keys for titlePlaceholder, editorArea description
