Summary by Sourcery

Generate a cryptographically secure random state parameter for OAuth consent URLs and update tests to validate its format.

Bug Fixes:

• Replace hardcoded default state parameter in getGlobusConsentURL with a dynamic random value to address security concerns

Enhancements:

• Introduce generateState helper that uses window.crypto.getRandomValues to produce a 16-byte hex string for OAuth state

Tests:

• Update getGlobusConsentURL tests to assert that the generated state is a 32-character hexadecimal string
