Added support for serverside rendering of members content (#10522)

no-issue

- Added member auth middleware to siteApp
- Passed member as context in routing service
- set Cache-Control: private for member requests
- fucked up some tests
- Added member as global template variable
- Updated tokens to have expiry of subscription_period_end
