Add IC Markets Server Integration for Account Connection

Implement IC Markets Server Support for Broker Account Connectivity.

Users need the ability to connect their IC Markets trading accounts to PF1, but IC Markets is currently not available as a server option in the account connection interface. This feature would add IC Markets to the list of supported brokers/servers within PF1's connectivity options, enabling users to link their IC Markets accounts for comprehensive trading analytics, performance tracking, and portfolio management alongside their other prop firm and personal accounts. The integration should support all standard PF1 functionality including trade importing, real-time data synchronization, performance metrics, and dashboard reporting to ensure IC Markets account holders can fully utilize the platform's trading analytics and management capabilities.
