bug(Button): Button hover/clickable outside border & missing token

### Is this a regression?

- [x] Yes, this behavior used to work in the previous version

### The previous version in which this bug was not present was

_No response_

### Description

When a override is added to a button, the button remains clickable and can be hovered outside the border. I found a token to override this behavior, but I can't get it to work. Additionally, I suggest improving the documentation by specifying the types of values accepted for the token.

```
@include mat.button-overrides((
filled-touch-target-display: none
))
```

Also there is no option to change outline color of outlined button when hovered/focused/pressed, only for disabled state? According to m3 design it should be possible:

### Reproduction

StackBlitz link: https://stackblitz.com/edit/q9bg7z8v?file=src%2Fexample%2Fbutton-overview-example-override.scss
Steps to reproduce:
1. Try to move cursor close to the button border

### Expected Behavior

Button should not be clickable or able to hover outside button border

### Actual Behavior

Button is clickable and can be focused outside border

### Environment

- Angular: 19
- CDK/Material: 19.2.1
- Browser(s): Chrome, Firefox
- Operating System (e.g. Windows, macOS, Ubuntu): macOS

从 src/example/button-overview-example-override.scss 中的 StackBlitz 复现开始，检查 mat.button-overrides 如何处理 filled-touch-target-display。将 hover、focus 和 click 区域与可见边框进行比较，并验证 outlined-button 的交互颜色是否可配置；当命中区域与边框匹配且已记录接受的 token 值时，即表示完成。
