Improve logging when interacting with server-manager

[marcelstanley]

📚 Context

Errors issued by the server-manager are currently being treated as warnings even in irrecoverable scenarios (re "session is tainted"). See sample node logs from debug session.

Such cases should be treated as errors and both the advance-runner and inspect-server should log them as such after such situations occur. These irrecoverable scenarios should be precisely logged that as well.

Additionally, the log levels used by both the advance-runner and inspect-server are not accurate and should be reviewed as well.

✔️ Solution

Update the advance-runner and inspect-server components to treat and log server-manager errors properly.
