[lib][web][native] Start using lastCommunicatedPlatformDetailsSelector from keyserverStore

Summary:
issue: https://linear.app/comm/issue/ENG-4462/refactor-lastcommunicatedplatformdetails-field
The second step is to start using the lastCommunicatedPlatformDetails from the keyserverStore, instaed of the one at the top level of redux store

Test Plan: ran yarn flow-all. Checked all places where we use useSelector from react-redux, and checked that none of them selects lastCommunicatedPlatformDetails.
