Allow deleting helpers directly from helpers panel (#28044)

* Allow deleting helpers directly from helpers panel

* Fix error handling in helper deletion logic

Address review feedback by improving the logic in _deleteHelper:
- Throw error when entity is not found in registry or component not loaded
- Move return statement outside of nested condition to ensure proper control flow
- Prevent fallthrough to config entry deletion for old-style helpers
