fix: remove unsupported FastMCP parameters to resolve TypeError

The FastMCP constructor was being called with unsupported parameters:
- allow_iframe=True (causing TypeError)
- allow_cors=True (also unsupported)

Removed these parameters to fix the crash when running uvx [email protected]

Fixes #19
