UI: Remaining requests percentage displays unrounded floating-point value

[miguel11nines]

Describe the bug

The "Remaining reqs." percentage in the UI displays unrounded floating-point values with excessive decimal places.
Example:
Remaining reqs.: 58.666666666666664%
Expected:
Remaining reqs.: 59%

Root Cause

The percentage is computed from integer division (e.g. remaining / total * 100) but the result is rendered directly without rounding, exposing IEEE 754 floating-point representation artifacts.

Suggested Fix

Round the percentage before display:

- `Remaining reqs.: ${(remaining / total * 100)}%`
+ `Remaining reqs.: ${Math.round(remaining / total * 100)}%`

### Affected version

v0.0.419

### Steps to reproduce the behavior

1. You can see it at the bottom right 
Remaining reqs.: 58.666666666666664%

### Expected behavior

Remaining reqs.: 58.67%

### Additional context
