fix: Catch errors about comparison CEL

[diegovb-sys]

Closes #5340

📑 Description

As I've posted in the Issue. There are some scenarios, where specific alert fields can be casted to other type than the expected.
An example is to use Mapping to dismiss an alert and after of that, read that field in a WF. The WF would expect a boolean value, but it will received a string, so this will cause a celpy error.

In order to face that problem, I've implemented (inside the Except) in WF and Incidents scopes a cast to the original values. (Using the ones defined in AlertDTO)
