Add explicit logging for JS module loading in server.js

Enhanced logging to verify object capture from globalVariables/*.js files

Changes to server.js loadGlobalVariables():
1. Extract returnedObject explicitly before assignment
2. Add detailed logging showing:
   - type: typeof the returned value
   - isObject: boolean check if it's an object
   - keys: number of properties in the object

Benefits:
✅ Verifies that vm.Script returns the object correctly
✅ Shows object has expected number of keys (11 functions)
✅ Confirms globalVariableContext[varName] receives the object
✅ Helpful for debugging module loading issues
✅ Makes the capture step more explicit and clear

Logging output shows:
  "Loaded global functions: googleDriveAdapterHelper",
  "type":"object",
  "isObject":true,
  "keys":11

This confirms the return object from googleDriveAdapterHelper.js
IS being added to globalVariableContext correctly!

Pattern verification:
- Line 60: const returnedObject = script.runInContext(context);
- Line 61: globalVariableContext[varName] = returnedObject;
- Result: globalVariableContext.googleDriveAdapterHelper = {11 functions}

Testing:
✓ Server starts successfully
✓ Module loads with correct object type
✓ All 11 functions captured
✓ Object available in VM context
✓ proxy.js can call googleDriveAdapterHelper.generateRequestId() etc.
