Additional Scenario & Contract Diversity Improvements

[IllianiBird]

Largely focused on flavorful fixed modifiers and terrain choices.

Pull request overview

This PR expands scenario and contract variety by broadening/adjusting allowed terrain selections, adding fixed scenario modifiers to certain templates/contracts, and introducing a synthetic “DropZone” terrain mapping to ensure suitable boards for grounded DropShip scenarios.

Changes:

• Added a new synthetic terrain type (DropZone) to biome map-type selection and to terrain-condition odds, and updated several DropShip-related scenario templates to use it.
• Updated StratConBiomeManifest.xml terrain/map-type mappings (including correcting HotMountainsDry/Wet naming and adding additional map types across multiple terrain keys).
• Adjusted multiple scenario templates’ allowed terrain types and added several scenario modifiers; moved certain contract modifiers toward “global” application.
