Add a tag when scenario used invalid/unknown severities

# Add a tag when scenario used invalid/unknown severities

## Context

Currently, the scenario which use an unknown severity (like `ihgh`instead of `high`) are marked with the flag `No Severity`.

## Expected
Scenario with invalid/unknown severities or countries should show in executions (with the same CSS as the No Severity) with the label `Wrong Severity!` (or `Wrong Country!`).

Start by locating the execution display that currently renders the `No Severity` flag and trace how scenario severity and country values are classified. Done means invalid or unknown values appear in executions with the existing styling and the requested `Wrong Severity!` or `Wrong Country!` label.
