Improve org_meta_return coherence on lists

[lyz-code]

Describe the bug

I feel that the current behaviour of org_meta_return on lists and checklists is really org_insert_heading_respect_content.

Steps to reproduce

So for example if we have the next file:

* Heading 1  <-- cursor here
  SCHEDULED: <2025-01-18>

If you press org_meta_return you get:

* Heading 1  
* <-- cursor here
  SCHEDULED: <2025-01-18>

If you press org_insert_heading_respect_content you get:

* Heading 1
  SCHEDULED: <2025-01-18>
  
* <-- cursor here

However if you have the next file:

* Heading 1
  - Line 1 <-- cursor here
    - Subline 1

If you press org_meta_return you get:

* Heading 1
  - Line 1
    - Subline 1
  - <-- cursor here

Which is closer to org_insert_heading_respect_content than org_meta_return as it respects the content

Expected behavior

From this file:

* Heading 1
  - Line 1 <-- cursor here
    - Subline 1

If you press org_meta_return you should get:

* Heading 1
  - Line 1
  -  <-- cursor here
    - Subline 1

If you press org_insert_heading_respect_content you get:

* Heading 1
  - Line 1
    - Subline 1
  - <-- cursor here

For me this change would be important because I use more often org_insert_heading_respect_content when dealing with headlines than org_meta_return so it would be a better ux experience for me to use the same key binding for what I'd expect on lists and checklists
