Added Discretionary Spending System Based on Wealth Trait

[IllianiCBT]

• Implemented a discretionary spending system using the "Wealth" trait, with rules inspired by A Time of War: Companion.
• Added configuration option to enable monthly wealth reinvestment via Campaign Options.
• Introduced "Extreme Expenditure" action for personnel, affecting wealth, loyalty, and generating reports.
• Expanded finances logic and resources to include "Wealth" as a new transaction type.
• Integrated spending calculations and options into the campaign process and GUI.OnWealth.tooltip` property to clarify fund reinvestment by campaign commanders.
• Removed extraneous whitespace from DiscretionarySpending.properties.

Dev Notes

This implements a system inspired by the Discretionary spending rules in ATOW: Companion. Optionally, each month the campaign commander will reinvest their discretionary fund, adding it to the campaign's coffers. The amount reinvested is based on the character's Wealth trait.

Alternatively, once a month, a character can perform extreme expenditure, which offers a significant payout but permanently reduces the character's Wealth by 1.

The rules for discretionary spending can be found in ATOW: Companion, pages 53-54. The differences between that system and ours are relatively minor:

• RAW the player should be able to choose if and when they use their discretionary fund. We have the use be automated each month.
• RAW if a character rolls a natural 2, or beats the check with an MoS of 6+, their Wealth is decreased or increased. I contemplated implementing this, but decided against it as due to the non-optional nature of our implementation it would cause Wealth to plummet very quickly and would cause users to view Wealth as not worth investing in.

Finally, I have to share this image from ATOW: Companion. As this is exactly how I view those players with multi-billion C-Bill campaigns:
