🚀 Player Contracts v1.1 — Security, Usability & Analytics Update

This update completely overhauls the input system to eliminate physical world exploits, enhances GUI interaction safety, introduces smart contract naming, and adds official bStats metrics support.

✨ What's New & Changed

🛡️ Safe Interactive Chat Input System

• Removed Physical Signs: Completely eliminated physical world oak sign placement. Players and griefers can no longer break input signs, harvest free items, or trap floating blocks.
• Interactive Chat Prompts: Item search, reward, amount, and duration inputs are now safely handled directly via chat.
• Clickable Cancel Button: Added a clickable [❌ Cancel] component with hover tooltips and command fallback (/contract cancelinput or typing cancel/iptal).
• Input Timeout: Automatically cancels inactive input prompts after 60 seconds to prevent state leaks.

🏷️ Meaningful Contract Naming & Localization

• Dynamic Contract Titles: Contracts are no longer identified by just a raw number (e.g. Contract #1). They now display meaningful item names and quantities (e.g. Diamond Contract (#1) / 64x Diamond (#1)).
• Comprehensive Placeholders: Full support for {id}, {amount}, and {item} across all language files.
• Auto-Migration: Automatically migrates legacy config.yml templates without breaking existing server configs.
• Robust Regex Extraction: Contract clicks now parse IDs using smart #(\d+) pattern matching regardless of custom title formats.

📦 GUI & Inventory Security Overhaul

• Duplication & Theft Fix: Added strict InventoryDragEvent protection to prevent players from dragging or stealing items/buttons out of menus.
• Shift-Click Safeguards: Isolated bottom inventory interactions and blocked illegal shift-transfers into plugin GUIs.
• Proper Partial Delivery:
  • Left-Click: Deliver all available items in inventory.
  • Right-Click: Deliver 1 stack (64 items) partially.
  • Shift + Right-Click: Deliver 1 single item partially.
• Claim Menu Auto-Refresh: Claim GUI now properly updates and reopens when partial claims occur due to full player inventory.
• Back Navigation: Added a ← Back button to the item search results browser.

📊 bStats Metrics Integration

• Integrated official bStats support.
• Added custom charts for:
  • Default Language Distribution (default_language)
  • Total Contracts Count (total_contracts)

🔧 Configuration Changes

• Updated contract_name, created, and accepted string keys in en and tr sections with {item} and {amount} placeholders.
