Accountant - Cross Realm Extension

🚀 New Features
Cross-Realm Tracking: View gold income, expenditures, and net profits across all your characters across all realms.

UI Integration: Added an All Realms toggle button directly into the main Accountant window for quick on-the-fly toggling.

Realm-Aware Dropdown: Enhanced character dropdown to show server names alongside cross-realm characters (Character Name - Realm).

Slash Commands: Added /acc realms and /accountant realms chat commands to toggle the cross-realm view instantly.

🛠️ Architecture & Compatibility
Modular Injection: Built as an independent bridge addon that hooks into Accountant's global namespace without modifying base files.

Update-Proof: Keeps core Accountant functionality intact, allowing the main addon to receive updates without breaking cross-realm features.

Patch 12.1.5 Ready: Fully updated and tested for World of Warcraft: Midnight.
