Issue Description

### Title
fix(widgets): `DigitsOptions` lacks `value` property option

### Description
In `packages/widgets/src/display/Digits.ts`, the `DigitsOptions` interface only declared `color?:

Color, omitting value?: string. Furthermore, the constructor read (style as any).valueinstead of checkingopts.value. Passing { value: '42' }inopts` failed to initialize the widget value.

### Expected Behavior
`DigitsOptions` should declare `value?: string`, and the constructor should accept `opts.value`.
