fix #758 logger tests

[susumutomita]

Description

This pull request fixes the logger test so that it no longer fails when importing LOG_LEVEL from logger.ts. Previously, there was a mismatch between LOG_LEVEL (a constant from @lit-protocol/constants) and LogLevel (an enum). This change ensures that both references can coexist, while favoring LOG_LEVEL for future compatibility.

Additionally, the test that checks creation timestamps (should order logs based on logger creation timestamp) has been corrected to compare loggerA.timestamp and loggerB.timestamp properly, instead of incorrectly matching a numeric timestamp against string IDs.

Type of change

• Bug fix (non-breaking change which fixes an issue)
• New feature (non-breaking change which adds functionality)
• Breaking change (fix or feature that would cause existing functionality to not work as expected)
• This change requires a documentation update

How Has This Been Tested?

• Locally:
  • Ran npx nx run logger:test --coverage and all tests passed without TypeScript errors.
  • Verified that LOG_LEVEL can be imported, and LogLevel still exists for backward compatibility.
