fix: overlap in download font list layout (#1900)

## Summary

Fix font download list layout overlap in Classic and RoundedRaff themes.
The font description was shown as a right-aligned value, causing text to
overlap with the font name on narrow screens.

### Changes
- Move font description from `rowValue` to `rowSubtitle` (second line)
- Show only status ("Installed"/"Update Available") as `rowValue`
- Fix Classic and RoundedRaff themes `rowValue` truncation (was fixed
60px, now dynamic)
