fix: Remove unsupported 'version' parameter from FastMCP initialization

Remove version parameter that causes TypeError in MCP SDK 1.12.3+
Refactor FastMCP initialization to use standard pattern
Extract instructions and dependencies as constants
Add create_server() function for better code organization
Maintain full compatibility with existing functionality
Fixes compatibility issue: TypeError: FastMCP.init() got an unexpected keyword argument 'version'

This occurs because the current MCP SDK (1.12.3+) does not support the version parameter in FastMCP initialization.
