de Translation missing "post.title"

### Site

phanpy.fulda.social

### Version

2026.02.24.48b2cf7

### Instance

fulda.social

### Browser

- Firefox 149, Linux
- Ungoogled Chromium, Linux
- Vanadium, Android

### Bug description

Clicking a post to see its detailed view (with possible replies), it always shows "post.title" in the top row, see attached screen shot.

### To reproduce

1. Go to phanpy instance (using multiple columns, should that matter)
2. Click on a post to see more of it.
3. Find the post.title at the top

### Expected behavior

Either nothing there or something thats an actual title (i wouldn't know what that would be, so nothing would probably be it).
