Make sure AI understands mines

LRM Thunder mines do very little damage and are likely to miss. Make sure the AI understands that placing them is valuable. Because ones that miss but land near a target are actually more valuable.

If possible it should value them higher when several enemies are close together.

The issue does not identify a file, test, or entry point, so first locate the AI logic that evaluates LRM Thunder mine placement. Review how mine damage, misses near targets, and groups of enemies are currently valued. Done means the AI consistently recognizes valuable placements, including near misses and clustered targets, with behavior covered by appropriate tests or scenarios.
