[Feature] Better Feedback Pipeline

[CommanderStorm]

Is your feature request related to a problem? Please describe.
The current pipeline for accepting coordinate/image/… changes is very labor-intensive.

Current workflow:

• User creates issue(s)
• We have to manually go into the code, add the change and sanity check if this makes sense
• We have to close the issue

Describe the solution you'd like
I would like this kind of feedback as a PR instead

Work Plan to get this done:

• Refactor the Feedback system to improve the code-adaptability
• change the current Feedback-API (renaming delete_issue_requested to deletion_requested)
• implement an API which can receive edit-requests
• add this change to the frontend (dependent on Vue3 Migration #200)
• Do some user Testing on the new workflow

Describe alternatives you've considered
I don't think there are better alternatives out there (at least I can't think of any)
