Localization: "Select All" and "Deselect All" are drawn as a segmented toolbar, so two one-shot actions look like a mode switch

Steps to reproduce:

1. Create a new project
2. Install the Localization package (com.unity.localization)
3. Open Edit > Project Settings > Localization and click "Create" to make the settings asset
4. Click "Add Locale" and look at the two controls directly below the locale list
5. Click "Select All" and watch for a pressed or selected state on the control
6. Compare the width and styling of those two controls with the "Add Locales" button below them

Actual results: "Select All" and "Deselect All" are drawn as a single full-width segmented toolbar - two joined segments with a shared border - which is the styling Unity uses for mutually exclusive mode switches. Neither segment takes a pressed or selected state when clicked, because both are one-shot actions rather than modes. They also stretch the full width of the window while "Add Locales" beneath them is a fixed narrower width, so the three controls in the footer are inconsistent with each other

Expected results: The two commands are drawn as ordinary buttons, since they perform actions rather than select a mode, and are sized consistently with "Add Locales"

Reproducible with versions: 1.5.12 (6000.5.7f1, 6000.6.0f1, 6000.7.0a6)

Tested on (OS): MacBook Pro - Tahoe 26.6.2

Notes:

• The mismatch is between control type and behaviour: segmented toolbars indicate a persistent choice, so the styling implies a state that these controls do not have and never display
