Fix editor errors - make Chili code safe for RmlUi mode

Fixed multiple errors when editors instantiate in RmlUi mode:

RCSS Fix:
- Removed 'word-wrap: break-word;' (unsupported in RmlUi)

Editor.lua Fixes:
- Made stackPanel creation conditional (only in Chili mode)
- Added guards to all stackPanel method calls
- Made field:Added() optional (only exists on Chili fields)
- Made tabbedWindow:SetMainPanel() conditional

Changes allow editors to instantiate without errors:
- Editors can be created in RmlUi mode
- Fields are collected in editor.fields
- No Chili UI is created (stackPanel=nil)
- Ready for RmlUi field rendering

All 16 editors can now be opened without crashes
