Implement vue math (#7759)

Adds support for entering math inside number widgets in vue mode

![vue-math_00001](https://github.com/user-attachments/assets/e8ed7e2a-511f-4550-bfdd-1c467972d30d)

Migrates components to simple html elements (div and button) by
borrowing styling from the (reverted) reka-ui migration in #6985. The
existing (evil) litegraph eval code is extracted as a utility function
and reused.

This PR means we're entirely writing our own NumberField.

Also adds support for scrubbing widgets like in litegraph

![scrubbing_00001](https://github.com/user-attachments/assets/890bcd28-34f4-4be0-908f-657e43f671b0)

### Known Issue
- Scrubbing causes text to be highlighted, ~~starting a scrub from
highlighted text will instead drag the text~~.
- It seems this can only be prevented with `pointerdown.prevent`, but
this requires a manual `input.focus()` which does not place the cursor
at location of mouse click.

(Obligatory: _It won't do you a bit of good to review math_)
