[ZEPPELIN-6298] Fix cursor-related issues in New UI's Paragraph
### What is this PR for?
**Description:**
Cursor behavior in the New UI’s paragraph needs to be fixed for several
cursor related actions, including double-clicking, running all above/below,
adding(clone), and removing paragraphs.
When **cloneParagraph()** is called, it internally calls
**addParagraph()**, which has already been tested. The same
addParagraph-related code is also applied in #5044. If either PR is merged
first, I will rebase accordingly. I have also confirmed that
**cloneParagraph()** works correctly through #5044.
Due to timing issues, I used `setTimeout` for **removeParagraph()** and
**doubleClickParagraph()**. Since this is in the UI area, it likely won’t have
major side effects, but I will look into it further.
**Expected:**
- When **doubleClickParagraph()** is executed, the cursor should move to
the end of the paragraph.
- When **runAllAbove()** or **runAllBelow()** is executed, the current
cursor position should be remembered, and after execution, focus should return
to the previous cursor position.
- When **addParagraph()** is executed, the newly added paragraph should
receive focus.
- When **removeParagraph()** is executed, focus should move to the
paragraph that takes the deleted paragraph’s place.
**Actual (New UI):**
- When **doubleClickParagraph()** is executed, the cursor moves to the
beginning instead of the end.
- After **runAllAbove()** or **runAllBelow()**, focus is lost completely.
- When **addParagraph()** is executed, the new paragraph does not
automatically receive focus.
- After **removeParagraph()**, focus may not move to the correct paragraph.
**[Appropriate action - Classic UI]**
https://github.com/user-attachments/assets/fc0066f7-4e03-4e3b-9d5b-2f33df415ba7
Run all above -> Run all below -> Double click .md paragraph -> Add
paragraph -> Delete paragraph
**[AS-IS]**
https://github.com/user-attachments/assets/f699f788-cf29-4c4c-8c47-2ef34d7962f0
Run all above -> Run all below -> Double click .md paragraph -> Add
paragraph -> Delete paragraph
**[TO-BE]**
https://github.com/user-attachments/assets/1206c524-103f-4328-85ee-04408073b628
Run all above -> Run all below -> Double click .md paragraph -> Add
paragraph -> Delete paragraph
