fix(webkit): STO-16 link field-multi-select option labels to their checkbox input

[robson-junior-azion]

Context - STO-16

QA report item STO-16 (Console 2.8.4): in Create Credential (/credentials/object-storage and the bucket's Credentials tab), clicking a capability's name or description, such as "Read Files", does nothing. Only the checkbox square responds. The checkboxes also have no accessible name.

Root cause

field-multi-select passed :id to the PrimeVue 3.35 Checkbox. That id lands on the root div.p-checkbox, not on the hidden <input>, so <label for="capabilities_readFiles"> pointed to a div. document.getElementById('capabilities_readFiles').tagName returned DIV.

Fix

Pass inputId instead of id. The input now carries the id, so the label is associated with it.

The toggle still happens only once: the label click turns into a click on the input, which bubbles to the Checkbox root, where PrimeVue's single onClick handler computes the new value from modelValue.

Impact

• Only consumers are the two FormFieldsCredential.vue in the console (Credentials and the bucket's Credentials tab).
• The label content is plain text (option.label and option.description, no slot), so there are no links or buttons inside it that a larger click target could interfere with.
• Nothing in console src/tests selects the checkbox by that id. The e2e helper tests/support/ui/storage.js uses focus + Space, which still works. It can now use getByRole('checkbox', { name }).

Validation

Playwright in Chromium against the Core/Form/FieldMultiSelect stories:

• getElementById returns INPUT ✅
• checkbox has an accessible name ✅
• clicking the label toggles on and off, once per click ✅
• clicking the box and pressing Space still toggle once ✅
• disabled: clicking the label does nothing ✅
• preselected values: only the clicked option changes ✅

With the change reverted, the same script fails (no checkbox with an accessible name).

• eslint on the changed file ✅
• pnpm webkit:build:dts and pnpm storybook:build not run
