Fix large number precision loss by using JSON_BIGINT_AS_STRING in ODataResponse

[Copilot]

Large numbers (like 80000000000000000000000) were being converted to scientific notation (8.0E+22) instead of preserving their original format when retrieving OData responses. This caused precision loss for services returning large number identifiers.

Problem

The issue occurred because ODataResponse::decodeBody() used json_decode() without the JSON_BIGINT_AS_STRING flag. When PHP encounters numbers larger than its integer limits during JSON parsing, it converts them to floating-point representation, which results in scientific notation and potential precision loss.

Solution

Modified the decodeBody() method in ODataResponse.php to use the JSON_BIGINT_AS_STRING flag in all json_decode() calls:

// Before
$decodedBody = json_decode($this->body, true);

// After  
$decodedBody = json_decode($this->body, true, 512, JSON_BIGINT_AS_STRING);

Testing

The fix has been validated with comprehensive tests covering:

• Large numbers: 80000000000000000000000 now preserved as string instead of 8.0E+22
• Normal data types: Integers, floats, booleans, arrays, and null values remain unchanged
• Both response types: Works correctly for both raw responses (entityReturnType = false) and Entity objects
• OData collections: Array responses with multiple entities containing large numbers
• Regression testing: All existing functionality preserved

Impact

Users can now reliably work with OData services that return large number identifiers without losing precision. The fix maintains backward compatibility while solving the precision loss issue described in the original problem.

Fixes #162.
