[Feature request] Add autocomplete label presets for Number Input Details

### Description

The Toolkit's **Form Element** annotations support `autocomplete` attributes, but **Number Input Details** doesn't have a pre-configured set of commonly used `autocomplete` values.

Users currently need to manually enter these values each time.

### Requested change

Add a secondary component set of autocomplete labels specifically for Number Input Details, with preset values for the most common autocomplete options. These would function the same way autocomplete labels work for other form inputs, but scoped to the values most relevant to number fields, such as:

- `cc-number` (credit card number)
- `cc-exp-month` / `cc-exp-year` (credit card expiration)
- `cc-csc` (credit card security code)
- `one-time-code` (SMS or authenticator codes)
- `postal-code` / `tel` (when used as number inputs)

### Why

Pre-configured autocomplete labels reduce the effort needed to annotate number inputs correctly and help ensure that commonly overlooked autocomplete values are surfaced to designers who may not be familiar with the full list of valid options.

Start by locating the Number Input Details component and the existing Form Element autocomplete label sets in the Figma toolkit. Compare their structure and behavior, then verify the new secondary set includes the requested number-related presets and follows the referenced autocomplete guidance.
