ui: Fix clipped status badge for download progress

Fixed visual issue where 'Downloading XX%' text was getting clipped/cut off
in the status badge.

Changes:
- Increased max-width from 100px to 140px (accommodates "Downloading 99%")
- Increased horizontal padding from 8px to 12px (better spacing)
- Status badge now displays progress percentages without truncation

Before: "Downloadi..." (clipped)
After: "Downloading 99%" (fully visible)
