Merge Request: Espionage Report Visibility Based on Espionage Level

Overview:

This merge request introduces logic to determine the visibility of information in espionage reports based on the difference in espionage levels between the attacker and the defender:

• Espionage Report Visibility Logic:
  Implemented functionality to adjust the visibility of fleet, defense, buildings, and research in espionage reports according to the number of probes sent and the difference in espionage technology levels.

Testing:

• Verified that the espionage report displays the correct information based on the difference in espionage levels.
• Ensured that the functionality works correctly for both higher and lower espionage levels.

Next Steps:

• Code review and merge upon approval.

Note:

• Further tweaks might be necessary based on additional feedback or testing results.

LGTM, merging!

PS: I didn't know of the existence for @forelse, nice to know that now 😄!

As an addition it would be nice to add a feature test for the espionage logic behaviour to help with potential refactoring later. I added a new separate issue for this which can be implemented later: #319.
