Campaign Stop Feature

[Jatin-35]

Summary

Add support for stopping an active campaign immediately from the dashboard.

Problem

Currently, once a campaign is started, there is no way to stop it before it completes. This becomes a problem when:

• A campaign is started by mistake.
• An issue is discovered during execution.
• The user runs out of balance or wants to avoid additional costs.
• The campaign needs to be paused for operational reasons.

Proposed Solution

Introduce a Stop Campaign action that allows users to terminate an active campaign.

Expected Behaviour

• A Stop button should be available for campaigns in the Running state.
• Clicking Stop should prevent any new calls from being initiated.
• Calls that are already in progress should be allowed to complete normally.
• The campaign status should change to Stopped once all active calls have finished.
• The campaign should be restartable later using the existing Resume functionality.

Benefits

• Gives users full control over running campaigns.
• Prevents unnecessary call charges.
• Improves operational flexibility.
• Provides a better user experience when mistakes or unexpected situations occur.

Additional Notes

The Stop action should only prevent scheduling new calls and should not abruptly terminate calls that are already in progress.
