Add documentation for the From<FPDecimal> for Uint256 implementation.

It's important to document how the conversion handles the sign of FPDecimal and any potential edge cases. This will help future developers understand the conversion process better and ensure correct usage.

Enhance the test coverage for test_into_u256.

The current test only covers a basic positive number conversion. Consider adding tests for edge cases such as large numbers, negative numbers, and zero to ensure the robustness of the conversion process.
