Fix Gamma API validation error and test alternative parameters

[berlinbra]

This PR fixes the Gamma API parameter validation error and attempts to find working parameters to get current markets.

What Your Logs Revealed

1. The order parameter causes a 422 validation error: "order fields are not valid"
2. The API works without the order parameter (returns 200 OK)
3. BUT it still returns old markets from 2020-2021 even with archived=false

What This PR Does

1. Removes the Invalid order Parameter

• The Gamma API doesn't accept the order parameter
• Removed it from both the tool schema and the request params

2. Tests Multiple Parameter Combinations

When the standard parameters don't work, the code now tries:

• Without archived parameter
• With just limit
• With live=true parameter
• With other potential parameters like status, resolved, enable_order_book

3. Enhanced Connectivity Test

The startup test now:

• Tests if archived=false actually filters old markets
• Tries different parameter combinations to find what returns current markets
• Reports which parameters successfully return 2024/2025 markets

4. Better Logging

• Warns when API returns old data despite archived=false
• Shows which parameter combinations are being tested
• Indicates when alternative parameters find current markets

Next Steps

Run this version to see:

1. If any parameter combination returns current markets
2. Whether the Gamma API is actually serving current data
3. If we need to use a different endpoint or API

The enhanced logging will show exactly what's happening and help us find the right solution.
