fix(logging): no log should be logged when loglevel is none

[5d]

Issue #

#3727

Description

The log level .none should not produce any logs, but it is currently misplaced in the LogLevel enum and has the same effect as .verbose.
In this PR, we have updated .none to be lower than the .error log level. Additionally, we have added a log level check guard condition in the log.error API.
