v1.6.4

Bug Fixes

• OAuth URL Structure: Fixed eBay OAuth authorization URL to use correct flow:
  • Uses signin.ebay.com/signin as entry point (was using auth.ebay.com/oauth2/authorize)
  • Passes consent URL (auth2.ebay.com/oauth2/consents) as encoded ru parameter
  • Fixes issue where OAuth URLs generated by setup script weren't working

Files Changed

• src/config/environment.ts - Updated getEbayAuthUrl()
• src/scripts/setup.ts - Updated OAuth URL generation in setup CLI
• tests/unit/config/environment.test.ts - Updated test expectations
