LudoDragon Global Combat Result Local Currency Display Fix

Server files:
- global-combat/get-my-result.php
- global-combat/get-leaderboard.php

Unity files:
- Assets/Scripts/GlobalCombat/GlobalCombatApiModels.cs
- Assets/Scripts/GlobalCombat/GlobalCombatSceneManager.cs

What it fixes:
- Result button loads a real result endpoint instead of opening empty.
- Result modal shows local amount won, e.g. D13,000.00 GMD.
- Leaderboard rows include the local reward/won amount.
- Supports settled events through global_combat_reward_settlements.
- Supports pending/live events by calculating expected rewards from reward tiers and player currency snapshots.
