fix(mosaic): focus the InputGroup input from noninteractive role content - #10637
InputGroup.Root focuses its input when the user clicks the group or plain addon text, and leaves the click alone when it lands on a control. The guard matched every element with a role, so a click on status, note or presentation content (a live character count, a hint) did nothing. The guard now lists the WAI-ARIA widget and composite roles, built into the selector from one array, and keeps [tabindex]. Buttons, links and role-only widgets inside the group keep their own click behavior.
A Counter story on the InputGroup page shows a role="status" character count. In swingset, clicking it left document.activeElement on body before and puts it on the group's input.cl-input after; clicking the Invalid story's in-group button focuses the button in both runs.
Fixes CORE-4107.

The group's click guard treated every element with a role as a control, so a click on status, note or presentation content inside the group did nothing. The guard now lists the WAI-ARIA widget and composite roles, and keeps tabindex, so only real controls keep the click. A Counter story with a live character count shows the case.
The input group now uses a defined list of widget roles when deciding whether clicked content is interactive. Tests cover clicks on noninteractive content and a switch-role element. The stories add a character-count example and describe how clicking its status text focuses the input.
Clicking some custom controls with fallback ARIA roles can unexpectedly focus the input. The impact is limited to those controls.

Explanation
The title names the main change: InputGroup now focuses its input when the user clicks noninteractive role content. The raw summary confirms the click guard in input-group.tsx now uses a fixed list of widget roles instead of matching any [role] element, and the test and story changes support the same fix. The title uses the fix(mosaic) prefix and fits the changeset's scope. It is 72 characters, which is within a normal title length.

Match widget roles in role lists.
role="switch checkbox" is a valid role list, but this selector does not match it. Clicking that widget therefore focuses the group input. WAI-ARIA resolves whitespace-separated role tokens in order. (w3.org)
Match role tokens and account for role precedence. Add a regression test for a widget with fallback roles.
