### Description

If I check the "prefer view" toggle in "view mode" to open a text file in view mode instead of edit mode it doesn't work if I open a text file from the Samsung file explorer with the option to open a text file always with markor, but it works if I open the text file from the markor "files" tab.

### Steps to reproduce

1. Check the prefer view check box
2. Close the markor app
3. Open a text file from the Samsung file manager with the markor choice to open every text files

Reproduce the issue by opening a plaintext file from Samsung's file explorer and compare it with opening the same file from Markor's Files tab. Trace the external file-opening path and the prefer-view setting; done means external launches honor prefer view after the app has been closed.
