Start the alignment process for a data job. The job must be in ready_to_start status. Pre-flight checks vary by job type:

• For principle_files jobs: a system_prompt must be set and files have been added to the data job
• For context_grounded_files jobs: files must have been added to the data job
• For context_grounded_vector_db jobs: a vector_database_id must be set
