### TL;DR

Improved formatting of RAM and GPU memory usage display in session list.

### What changed?

- Added a new static method `_prefixFormatWithTrailingZeros` to format numbers with a fixed number of decimal places.
- Updated the RAM and GPU memory usage display to use the new formatting method, ensuring consistent decimal places.

### How to test?

1. Open the session list view.
2. Create or connect to a session with active resource usage.
3. Verify that the RAM and GPU memory usage values are displayed with two decimal places consistently.
4. Check different sessions with varying resource usage to ensure the formatting is applied correctly in all cases.

### Why make this change?

This change improves the readability and consistency of resource usage information in the session list. By formatting the RAM and GPU memory usage values with a fixed number of decimal places, it becomes easier for users to compare resource utilization across different sessions at a glance.
