ui: publishing an unmodified draft skips validations

[miguelgrc]

It is possible to, for example, publish draft with an unfilled required field if it has not been modified. This should not be allowed.

To replicate:

• Create a cms_analysis draft > publish it > it should publish without issues [WRONG BEHAVIOR]
• Edit any field in the draft (other than the required cadi_id) > save the draft > publish it > it should throw an error [DESIRED BEHAVIOR]
