fix: Improve tool metadata and dropdown state management (#7257)

* 🐛 (component.py): Fix issue where tags attribute may not exist on tool object
🐛 (index.tsx): Fix bug where value may not be included in options before setting it

* 🐛 (component.py): fix issue where tags list is empty if tool.tags is not defined, now default to [tool.name] to ensure at least one tag is present
