Fix SSR contacting /status endpoint

SSR is currently contacting the /status endpoint. This is done to check if it should display the status warning icon

I am currently manually testing to ensure that all regressions have been addressed

Changes

• Changed: If the website status API request times out, the /status page's "Server Connection" status now shows "Unhealthy" instead of "Unknown"
• Bug fix: Change the website status service to not make API calls in SSR environments
• Bug fix: Change the website status icon to assume a healthy connection (to remove cumulative shift). The warning icon used to flash and disapear when the website initially loaded because it'd assume that an "undefined" response from the API (the /status request is pending a response), was a bad response. It now assumes that if we haven't gotten a response the API is healthy (if the /status request times out, the status is assumed "unhealthy" and the warning icon is shown)
• Bug fix: Previously, if the user lost internet connection, the website status service would error and API calls would stop. This would mean that when the user regained internet connection, the warning icon would not disapear. This has now been fixed.
• Upgrade Karma from version 6.4.2 -> 6.4.3
