🔧 Fix authentication flow and collaborator management

✅ Fixed server action import issues (ensureUserProfile)
✅ Fixed collaborator limit logic - only show subscription modal at 2+ collaborators
✅ Replaced all console.log with custom logger helper (production-safe)
✅ Fixed import conflicts between client/server utils
✅ Improved user experience with better plan limit messaging
✅ Added comprehensive debugging for authentication flow
✅ Fixed subscription modal to show actual plans instead of 'contact support'
✅ Updated documentation with working solutions
✅ All authentication issues resolved and tested

- Login/signup now works without 404 errors
- Collaborator search shows clear plan limits upfront
- Subscription modal only appears when actually needed
- Production-safe logging implemented throughout
- Build, lint, and format all passing
