[Feat] War Declaration System #37

Summary

Implement a formal war declaration system that goes beyond simply setting enemy relations. Wars should be structured events with objectives, victory conditions, costs, and rewards.

Features

War Declaration

• /f war declare <faction> — Initiate a formal war (requires leader/officer)
• War declaration fee deducted from treasury (TransactionType.WAR_COST already exists)
• Target faction receives notification with option to prepare
• Optional war declaration cooldown (configurable)

War Mechanics

• Objectives: Configurable victory conditions (e.g., destroy core block, capture territory, reach kill count)
• Victory conditions: First to complete objectives, or highest score when timer expires
• War end conditions: Surrender, timer expiration, objectives met, mutual agreement
• War costs: Initial declaration fee, ongoing resource drain (optional)

War Statistics

• Track kills, deaths, territory captured/lost during war
• War history log per faction
• Display active wars in faction info/GUI

Commands

• /f war declare <faction> — Start a war
• /f war surrender — Surrender current war
• /f war status — View active war details
• /f war history — View past wars

GUI

• War page in Modules section (currently shows "Coming Soon" placeholder)
• Active war dashboard with live stats
• War history browser

Existing Infrastructure

• TransactionType.WAR_COST — Already defined for war fees
• RelationType.ENEMY — Already handles enemy relations
• GUI placeholder in FactionModulesPage
