Update status endpoint to return non-200 if any component isn't reachable

[maxsibilla]

If any current check fails return a 500 status code, otherwise return a 200.

Additionally check the following, add an entry to the status json for each and return a 500 if any fails:

• A call to https://entity.api.sennetconsortium.org/doi/redirect/SNT577.KHFG.572 returns an http 307 status code with a redirect URL that, when doing a GET on returns a status code in the range 200 <= code <= 299

• A call to https://doi.org/10.60586/SNT577.KHFG.572 returns an http 302 status code with a redirect URL that, when doing a GET on it returns a status code in the range 200 <= code <= 299
