fix(tests): prevent permission dialogs during test runs

Add MOLE_TEST_MODE=1 checks to skip AppleScript osascript calls
and sudo operations that trigger system permission dialogs during tests:

- lib/check/all.sh: Skip login items listing
- lib/clean/apps.sh: Skip running app detection
- lib/clean/user.sh: Skip Finder trash operations and sudo test calls
- lib/core/log.sh: Skip sudo status check in debug log
- lib/uninstall/batch.sh: Skip login item removal

Also add MOLE_TEST_MODE=1 export to all test files that load
these modules to ensure consistent test isolation.

lib/core/log.sh
