feat: introduce canonical active prop to Chip component family

[cb-ekuersch]

What changed? Why?

Replaces Chip's invertColorScheme / inverted emphasis with a canonical active state API across web and mobile.

• Add active, activeBackground, and activeColor to Chip, InputChip, and SelectChip (web + mobile).
• Keep inverted-scheme compatibility while active is the public emphasis path; InputChip remains active by default (active={false} for the quieter look).
• Derive SelectChip's active state via shared getSelectChipActive and tighten SelectChip/SelectChipControl prop types with light refactor/reorganization of types.
• Update TabbedChips, stories, Code Connect, docs, and Legend examples to the new active API.
• Further expand the example customer-component-config playground with new components: SelectChip, InputChip, TabbedChips, CheckboxCell and RadioCell

N/A

UI changes

select chip docs	input chip docs	chip docs

Example utilizing active colors in component config:

select chip active	select chip inactive

Testing

How has it been tested?

• Unit tests
• Interaction tests
• Pseudo State tests
• Manual - Web
• Manual - Android (Emulator / Device)
• Manual - iOS (Emulator / Device)

Testing instructions

• Spot-check Chip, InputChip, MediaChip, and SelectChip stories for default vs active (and activeBackground / activeColor overrides).
• Confirm InputChip still looks active by default and quieter with active={false}.
• Open the expo playground Customer Component Config screen: toggle individual Configured switches and Toggle all, and verify Chip/InputChip/SelectChip/TabbedChips configured styles.
• Run unit tests for Chip, InputChip, SelectChip, and getSelectChipActive.

I'm concerned that active flipping now remounts the select control. createSelectChipControlWrapper is memoized on the chip props, and active is now one of them, so the first selection (and clearing back to empty) produces a new component type for SelectControlComponent. React unmounts/remounts the whole control: the trigger button loses focus and AnimatedCaret restarts. Previously the deps were effectively static. A stable wrapper that reads chip props from a ref/context (or passing chip props through Select) avoids this.
