[6827] Pinia Task 10 - product-expert-operator-agent

[n-lark]

Description

See details here.

⚠️ This is cut from 6826-pinia-task-9-product-expert-ff-agent to daisy chain.

No UI test plan required for this task.

The product-expert-operator-agent Pinia store has no direct component consumers — all access goes through the parent product/expert Vuex module, which remains unchanged. There is nothing new visible in the UI as a result of this PR.

The only user-facing behaviour to verify is:

• Login — no console errors on page load
• Logout — useProductExpertOperatorAgentStore().$reset() fires cleanly; no console errors

All store logic (state initialisation, reset(), setSessionCheckTimer(), setSelectedCapabilities(), getCapabilities(), and the capabilities getter) is covered by the 8 unit tests in test/unit/frontend/stores/product-expert-operator-agent.spec.js.

Both the ff-agent and operator stores are used intensively within the expert store dynamically, wherever [state.agentMode] is used
