Multiple locations had unquoted bash variables in AWK BEGIN blocks
that could fail if variables were empty or malformed:
- Lines 3369, 3375: Added fallbacks to domain/traffic counts
- Lines 2338, 2383: Added error handling to percentage calculations
- Lines 2657-2663: Added guards to bandwidth calculations
- Line 2686: Added guards to domain traffic breakdown calculations

error suppression to prevent syntax errors from empty values.
