* test: Enhance `Num<Fr>` testing

- Enhanced property testing coverage and introduced new tests for `U64` and `Scalar` types.
- Provided comprehensive test scenarios including basic operations, assertions, checking sign, and "lesser" properties.
- Improved coverage for scalars and u64, encompassing overflow/underflow cases and edge conditions.

Closes #52

* refactor: Refine numeric comparison in `prop_lesser` function

- add a direct comparison from #738
