FIX: Remove all debug messages from php-analyzer functions

Removed echo statements to stderr that could interfere with function
return values if captured together with stdout:
- calculate_balanced_memory_allocation()
- calculate_balanced_memory_allocation_per_domain()
- Domain traffic analysis messages

These could cause similar 'integer expression expected' errors if
called with stderr capture (2>&1)
