ISSUE: User reported alignment tools not showing and delete not working
ROOT CAUSE: Over-complicated toolbar config with too many additions
- Added Strike, Subscript, Superscript (not in standard build)
- Added Image (might not be in build)
- Added ShowBlocks (might not be in build)
- Added extra config options that might conflict
SOLUTION: Return to ORIGINAL working toolbar + ONLY alignment buttons
- Restored original toolbar config that was working
- Kept ONLY the alignment row: JustifyLeft, Center, Right, Block
- Removed Strike, Subscript, Superscript, Image, ShowBlocks
- Removed extra config: allowedContent, entities, fillEmptyBlocks, etc.
- Delete function unchanged (already fixed in commit d025111)
TOOLBAR NOW:
✅ Original working buttons (Source, Undo, Redo, Bold, Italic, etc.)
✅ Text alignment buttons (JustifyLeft, Center, Right, Block) - USER'S REQUEST
❌ Removed bonus features that caused issues
This is minimal change - only adds what user asked for.
