Fix Windows path compatibility in absolute path tests

The tests were comparing string representations of Path objects, which
fails on Windows where Path('/tmp/file.json') becomes 'D:\tmp\file.json'.

Changed assertions to compare Path objects directly, which works
cross-platform by normalizing paths internally.

Fixes:
- test_get_local_state_path_env_absolute
- test_get_upstream_cache_path_env_absolute
