Fix Monaco editor @entangle error with unique HTML IDs

**Problem:**
Monaco editor was receiving unique HTML IDs (e.g., "customLabels-a09a7773")
and using them in @entangle(), causing errors:
"Livewire property ['customLabels-a09a7773'] cannot be found"

**Root Cause:**
Monaco editor template uses @entangle($id) to bind to Livewire properties.
After our unique ID fix, $id contained the unique HTML ID with suffix,
not the original property name.

**Solution:**
Pass $modelBinding (original property name) instead of $htmlId to Monaco
editor component. This ensures @entangle() uses the correct property name
while HTML elements still get unique IDs.

**Result:**
✅ Monaco editor @entangle works correctly
✅ HTML IDs remain unique
✅ No Livewire property errors
