Adds a simple health api endpoint

[Bentlybro]

This PR adds a health api endpoint for uptime monitoring.

The output from /api/health looks like this

{
  "status": "healthy",
  "message": "",
  "timestamp": "2025-01-31T14:57:01.764Z",
  "subsystems": [
    {
      "name": "api",
      "status": "healthy",
      "message": ""
    },
    {
      "name": "database",
      "status": "healthy",
      "message": ""
    }
  ]
}

Hope this helps 😃

Hi @Bentlybro, thanks.

Is this functionality for Significant-Gravitas/AutoGPT#9378?

I don't think we are planning to add a separate health endpoint. You can check that iffy.com responds with a 200. In the future we might add a status page.

Hello @s3ththompson yes it is partly for that, i have gone ahead and added it to the locally hosted version we are using! and no worried for not adding it I just thought id see if it was of any use 😄

I have some questions for you regarding Iffy, is there a good platform i can reach out to you on? discord maybe? its about allowing extra data to be send via a ingest request like "metadata" and have that be sent back over the webhook
