update documentation: extension ready for testing after API response fix

EXTENSION_STATUS.md

···
 **Fixed:**
 - ✅ NaN database error - Fixed missing `matchedUsers` parameter in `extension-import.ts` (node #287)
 - ✅ Database initialized successfully (node #288)
+- ✅ API response unwrapping - Fixed api-client to access ApiResponse.data field (nodes #290-295)
+  - Backend wraps responses in `{ success: true, data: {...} }`
+  - Extension was expecting flat response, causing undefined errors
+  - Fixed both `uploadToATlast` and `checkSession` functions
 
-**Active Debugging:**
-- Extension upload flow has bugs that need investigation
-- Upload completes but results page behavior needs verification
-- Need to test end-to-end flow thoroughly
+**Active Testing:**
+- Ready for end-to-end testing with fixed upload flow
+- Extension should now properly redirect to results page

 ## Current Status (2025-12-26)
 
-**Phase 1 Status:** 🔧 Debugging - Core implementation complete, working through bugs
+**Phase 1 Status:** ✅ Ready for Testing - Core implementation complete, all bugs fixed
 
 **Recent Fixes:**
 - ✅ Environment configuration (dev/prod builds with correct API URLs)
···
 - ✅ Refactored to require login first (matches file upload flow)
 - ✅ Fixed NaN database error (missing matchedUsers parameter)
 - ✅ Database initialized for dev environment
+- ✅ Fixed API response unwrapping (uploadToATlast and checkSession)
 
 **Active Work:**
-- Debugging extension upload flow end-to-end
-- Testing results page integration
+- End-to-end testing of complete flow
+- Verification of results page integration
