Propagate changes after modifying OD model

[samfreund]

Description

This PR adjusts how model modification is handled. Any updates to metadata, or deletion is handled in the frontend after sending data to the backend. Any creation of models occurs in the backend, and we push an update to the frontend.

This PR also fixes a typo in PhotonUtils which meant we hit the wrong endpoint when an IP was passed into the status check.
