- Remove duplicate action handlers (edititem, deleteitem, createitem, etc.) from DS4ActorSheet and DS4ItemSheet
- Fix editImage method reference from static to prototype in DS4ActorSheet
- Add capitalize helper to handlebars-helpers.ts for dynamic action name generation
- Update control-button-group.hbs and add-button.hbs templates to use concat and capitalize helpers
- Ensure consistent camelCase naming for all action handlers (editItem, deleteItem, createItem, etc.)
This resolves action handler conflicts and improves maintainability by using dynamic template generation
instead of hardcoded conditional logic.
