refactor: remove EnhancedComposer backward compatibility

- Remove EnhancedComposer shim and old backup file
- Update all imports to use new Composer from ./composer
- Fix editor command implementations for link operations
- Fix dropdown hook usage with proper reactive patterns
- All 5 components now directly import the modular implementation
