[6826] Pinia Task 9 - product-expert-ff-agent

[n-lark]

Description

See details here.

⚠️ This is cut from 6825-pinia-task-8-product-assistant to daisy chain.

No UI test plan required for this task.

The product-expert-ff-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 behavior to verify is:

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

All store logic (state initialization, reset(), setSessionCheckTimer()) is covered by the 18 unit tests in test/unit/frontend/stores/product-expert-ff-agent.spec.js.

This is not right, both the ff-agent and operator stores are used intensively within the expert store dynamically, wherever [state.agentMode] is used

see above comment

[cstns]

we should also rename the store and agent key while we're at it. We settled on insights with product after a couple of variations and we should also switch to it to avoid disconnects moving forward
