[BE] Game Event Integration

[Meshmulla]

closes #296

This PR adds the perks/boost engine directly into the core gameplay mechanics to ensure boosts dynamically affect game events in real time.

Boost effects now influence key gameplay actions such as dice rolls, movement, rent calculations, tax handling, and income logic.

Changes Included:
Injected boost engine into main game logic
Hooked boost processing into: Dice roll logic (e.g., extra roll). Movement handling (e.g., free movement). Rent calculation (e.g., rent reduction)

Property purchase logic
Tax and income events (e.g., tax immunity, double income)
Implemented priority rules for resolving multiple active boosts
Optimized execution to avoid performance impact
