## Description
<!-- Describe your changes in detail -->

this pr fixes the issue where cookies are not being set when hitting user apis.

- we need to set cookies. but cypress does not directly support that 
- `cy.setCookie()` method does not persist outside of the `it()` block
- in order to make it persist, we need to set session using `cy.session()` method in the `beforeEach()` hook

closes #6977

this pr, of course, does not fix the hooks (caching) issue.

every failure here is related to assertion and `globalState` where `connectorId` and `mcaId` not getting updated. This can be picked up a separate PR since the fix done in this PR is `P0`
