Fix trailing comma and indentation inconsistencies in test files

[Copilot]

Summary

This PR fixes code style inconsistencies in 126 test files where the make_instance method's else block had incorrect formatting.

Problem

The test files (generated by OpenAPI Generator) had two formatting issues in the else block of their make_instance methods:

1. Trailing comma: The last parameter had an unnecessary trailing comma
2. Incorrect indentation: The closing parenthesis was indented at 8 spaces instead of 12 spaces, breaking alignment with the return statement

This created inconsistency between the if include_optional: block (correctly formatted) and the else: block (incorrectly formatted).

Example Fix

Before:

def make_instance(self, include_optional) -> DraftPosition:
    """Test DraftPosition"""
    # ...
    if include_optional:
        return DraftPosition(
            name = '',
            abbreviation = ''
        )
    else:
        return DraftPosition(
            name = '',
            abbreviation = '',    # ← Trailing comma (incorrect)
        )                          # ← 8 spaces (incorrect alignment)

After:

def make_instance(self, include_optional) -> DraftPosition:
    """Test DraftPosition"""
    # ...
    if include_optional:
        return DraftPosition(
            name = '',
            abbreviation = ''
        )
    else:
        return DraftPosition(
            name = '',
            abbreviation = ''     # ← No trailing comma (correct)
            )                      # ← 12 spaces (correct alignment)

Changes

• Fixed 126 test files in the test/ directory
• Removed trailing commas from the last parameter in else blocks
• Adjusted closing parenthesis indentation from 8 to 12 spaces for proper alignment

Verification

• ✅ All 194 tests pass
• ✅ No syntax errors (verified with flake8)
• ✅ No security vulnerabilities (verified with CodeQL)
• ✅ No functional changes - only formatting corrections
