feat(studio): endpoint to retrieve incident status (#41355)

Incident status banners/alerts should be automatically determined from
the status page, rather than being manually configured.

Adds a new endpoint, /api/incident-status, to return information about
active incidents. This information is fetched from the StatusPage API.
The endpoint is cached to reduce number of third-party API requests.
