Nivesh Dandyan 15ea560863 fix: change ContentLength internal type from usize to u64
This fixes the test failure on 32-bit platforms where the large
value test (u64::MAX) would fail because `usize` cannot hold values
larger than 4GB on 32-bit systems.

According to RFC 9110, Content-Length can be any valid unsigned
64-bit integer, and it's reasonable to have content larger than
4GB even on 32-bit systems (e.g., streaming large files).

Changes:
- Change ContentLength inner type from usize to u64
- Update into_inner() return type to u64
- Update FromStr to use u64 parsing
- Add From<u64> implementation
- Update From<usize> to convert to u64
- Add PartialEq/PartialOrd implementations for u64
- Update usize comparisons to properly convert
- Fix test to use u64 literal suffix
- Update json.rs to convert u64 to usize with try_from

Fixes #3812
