* fix: reconnect web components after session expiration After session expiration, Flow client in webcomponent mode send a GET request to the server to re-initialize itself with a valid session cookie. However, the XHR call is done with the withCredentials flag set to false, making the browser ignore the Set-Cookie header in the response. This change forces the withCredential flag to true for resync request so that the new cookie can be handled by the browser and reused in the subsequent request that re-intitializes the embedded component. If PUSH is enabled, it also restores the connection after resynchornization request to make sure pending invocation queue, and especially the webcomponent connected events, can be flushed correctly and sent to the server. Also temporarily suspends hearbeat during resynchronization request to prevent issue with concurrent requests, potentially causing duplicated session expiration handling on the client. Fixes #19620 * add tests
