fix(log messages) homogenize the emojis used for user output messages

[dduportal]

It's a "short term" fix to ensure that the log messages have the same behavior and all use the same emoji.
It also improve code readability as it's easier to understand the constant result.ATTENTION than \u26A0.

Please note the following changes:

• As we use the package name result, when a variable had a conflicting name then it had been changes (3 occurends, 2 are in the AMI package)
• There was slight differences of emojis (2416/2415 for instance) that have been simplified to all use the same from the result package
• Sources only have FAILURE or SUCCESS states
• Same for conditions: only FAILURE or SUCCESS states
• For targets, FAILURE indicates a real error, while SUCCESS is used when nothing had been changed, and ATTENTION when a change is expected (diff) or applied (apply).

Please note that a long term fix is to implement a custom logger package that would provide explicit method such as ValidationErrorLog(), SuccessErrorLog(), ContentChangedLog(), FailureLog() etc. to move the multiple usages of emojis to a central place, and get rid of the result package.

Thank you.
Iit goes in the right direction.
The next step is to have a specific package for UI
