feat(frontend): add backup and redeploy app action with auth dialog

[drik98]

Summary

This PR improves backup UX by adding an app-level Back up / Redeploy action directly in each app card menu, so users no longer need to call the REST API manually.

What Changed

• Added a new dropdown action in ReviewAppCard:
  • Shows Back up for deployed apps
  • Shows Redeploy for backed-up apps
• Added new confirmation modal: BackupAppDialog.vue
  • Same confirmation pattern as shutdown
  • Auth-aware warning: You need to be logged in to back up or redeploy apps.
  • Refactored existing dialogs to de-duplicate logic
• Added Vuex app-state toggle support in frontend/src/store/index.js:
  • New action: changeAppState
  • Calls PUT /api/apps/{appName}/states/
  • Reuses fetchAndPoll for async task completion handling
• Backed-up apps are now displayed under the "My Previews" section if the owner matches
  • Backed-up apps now have a badge in the heading indicating they are backed-up to distinguish them better
• Improved the logic around expansion of container of a review app
  • Added unit tests to document the intentions better

Thanks for stepping in here. I was planning to work this today or tomorrow. Looks very promising to me. However, there is one thing I like too ask you: can you check if there is a nice way of making the dashboard a bit more compact by moving the backups associated with the logged in user into the same slot “My Previews”?

@schrieveslaach I think we will also have to remove the Logs link of the service of an back-upped app right? Currently we can still open the logs window but the API returns 400.

Thanks for putting in the effort for making the dashboard more compact and for fixing the input focus issue. I really appreciate.

The only missing part is the isBackupsEnabled condition.

If you are so kind, pleas, go ahead. Sounds reasonable.

Changes were a bit more complicated then I imagined. I added some unit tests to bring some clarity about the logic when we actually render the expansion panel.
