FOUR-26241: Fix process owner validation on update and show validation alert

[eiresendez]

Issue & Reproduction Steps

Saving a process with an empty owner caused a server error because processes.user_id is not nullable.

Solution

• Added a ProcessUpdateRequest FormRequest to validate updates and require user_id when provided.
• Switched ProcessController@update to use the FormRequest instead of inline validation.
• Added a generic 422 alert in the process edit UI to surface validation errors to the user.

How to Test

1. Open any process and clear the “Process Owner”.
2. Click Save.
3. Verify you see a validation alert and an inline error and no server error occurs.
4. Set a valid owner and save again; confirm it saves successfully.
