feat: controller mode with SallyAgent, add salt and logging args, health endpoint, curls config, better logging

[kentbull]

This PR does the following:

• Adds the proper "sally" block to the Habery bootstrap config file so that the proper controller /loc/scheme reply message is added to the OOBI resolve output.
• Adds a --salt arg to sally server start and passes it through to the Habery creation so that separate initialization and inception are no longer required.
• Adds a --loglevel command to sally server start so that the log level can be configured by command line argument.
• Adds a healthcheck endpoint at /health that shows a health message, the version of Sally, and some basic metrics.

A sample healthcheck response looks like this:

{
  "message": "Health is okay. Time is 2025-02-06T23:49:47.673704+00:00", 
  "version": "0.9.4", 
  "counts": {
    "senders": 0, 
    "iss": 0, 
    "rev": 0, 
    "recv": 0, 
    "revk": 0, 
    "ack": 0
  }
}

I force-pushed this today after updating it to the latest code since merging 0.10.0 to main. This will be v1.0.0.

Once I test it again and verify both indirect and direct mode continue to produce the same results then I will take this from draft to ready to review.

closing in favor of the new direct-mode branch PR.
