Adds a status embed for the PingPong status page
(https://pingpong-hks.statuspage.io). Whenever an incident is created,
or maintenance is underway, users will get a banner in the bottom right
corner of the page informing them of the current app status.

Notes:
- The status embed is set to only appear when the user is logged in and
onboarded for now, but we can decide to add the status embed in
additional places, e.g. the log-in page.
- With this addition, we can use the [StatusPage
API](https://developer.statuspage.io) in the future to update our status
page server-side, and the [Public Page
API](https://pingpong-hks.statuspage.io/api) to inform users of any
upcoming maintenance.
- We should be able to use the same Public Page API from OAI's page
(https://status.openai.com/api) to programmatically monitor for
incidents and update our Status Page accordingly.
