UI misalignment in Unity Accelerator settings: "Check Connection" button incorrectly left-aligned and help box not full-width

Steps to reproduce:

1. Create a project
2. Download and install the latest Accelerator/CacheServer build on your machine
3. Connect your Unity project to the Accelerator instance you have installed
4. Open "Project Settings" window (Edit -> Project Settings ->Editor)
5. Find "Accelerator cache Server (project specific) section
6. Set "Mode" to "Enabled"
7. Set "IP address" to "127.0.0.1"
8. Click "Check Connection"
9. Observe where the "Check Connection" button and help box are displayed

Actual results: "Check Connection" button is displayed on the left side of the window. The help box is not equal to the width of the input fields or the entire window.

Expected results: The button should be displayed on the right side of the window, and the help box should fill the window's full width. The placement of the same components should be consistent.
