fix(editor): correct TeleportElement option and improve dropdown

Correctly set the value for the Teleport option in the element creation
form, ensuring that elements are correctly classified. Enhanced dynamic
data fetching for scenes and categories to populate the destination
dropdown based on the scene's category, improving user experience in
specifying teleport destinations. Resolved an issue with event
propagation by explicitly setting the button type for dropdown items,
preventing form submission on selection. This change streamlines the
process of creating teleport elements and selecting destinations within
the editor, making it more intuitive and error-free.

- Removed outdated TODO comment related to element drags handling.
- Removed unused rotation input fields for a cleaner UI.
- Added conversion function `thetaToCartesian` for future
functionalities.
