Add warning message when changing Observation Definition status

[anaghathedesigner]

Description
Currently, when a user changes the status of an Observation Definition, it can potentially affect or disrupt any Activity Definitions that are linked to it. Because this action has downstream consequences, we need to ensure users are fully aware of the impact before they finalize the status change.

Proposed Solution:
Implement a confirmation/warning message on the Observation Definition form. When a user attempts to change the status, they should be intercepted with a warning alerting them to the potential impact on related Activity Definitions.

Steps to Reproduce:

• Select a facility

• Settings-> Observation Definition

• View one of the Observation Definitions from the list -> Edit

• Modify the status of the Observation Definition, it changes without any warning.

Screen Recording:

Status.Change.in.Obsvtn.dfn.mp4

Proposed Solution
A warning modal or dialog appears preventing the immediate change of status.

Expected Behaviour of the Modal
When the modal appears, there should be a blanket over the edit form of the Observation Definition. When clicking outside the modal, it should be closed.

We should avoid a heavy alert dialog, as long text can overwhelm users. A clear title and a short explanation of the impact should be enough. I'm not sure whether we can fetch and display those AFFECTED ACTIVITY DEFINITIONS list.
Since this change impacts the Activity Definition and its active observation requirements, keeping the current status should be the primary action. This prevents accidental changes.
If the user intentionally wants to proceed, changing the status should be a tertiary action, rather than a destructive primary button.

Checked with @yaswanth whether we can fetch and display the affected Activity Definitions list. He mentioned that we cannot fetch the list, so I updated the warning message accordingly.
