Source and Translation Tests

[saengel]

Title: Verify handling of source and translation texts.

Test:

1. Check indexes with different states of text availability:
   • Only RTL source
   • Only LTR source
   • Only RTL translation (e.g., Treatise on Logic 7)
   • Only LTR translation (e.g., From Sinai to Ethiopia)
   • RTL source and translation (e.g., Tanakh Hebrew and Yiddish)
   • LTR source and translation (e.g., Rav Hirsch community translation)
   • RTL source and LTR translation
   • LTR source and RTL translation (e.g., What is the Talmud)
2. For each state, check 3 view states: source only, translation only, source and translation (showing an empty column if one is missing).
3. Verify layouts in the text menu and ensure proper display (direction and alignment) for any layout.
