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

Start with the StackBlitz reproduction at src/example/button-overview-example-override.scss and inspect how mat.button-overrides handles filled-touch-target-display. Compare the hover, focus, and click area with the visible border, and verify whether outlined-button interaction colors are configurable; done means the hit area matches the border and the accepted token values are documented.
