From c1f81cfaddc8df523eb49f564ebf91253a6f137d Mon Sep 17 00:00:00 2001
From: Kailash Nadh <kailash@nadh.in>
Date: Sun, 6 Apr 2025 19:23:51 +0530
Subject: [PATCH] Fix compatibility issues with `master`.

- Fix merge conflicts.
- Simply logic in campaign preview handler.
- Remove redundant `GetCampaignForPreviewWithTemplate()` and switch to the old
  query that optionally takes a template.
- Fix Vue linting issues.
