Failed auto-uploads are not retried

### ⚠️ Before posting ⚠️

- [x] This is a **bug**, not a question or an enhancement.
- [x] I've [searched for similar issues](https://github.com/nextcloud/android/issues) and didn't find a duplicate.
- [x] I've written a clear and descriptive title for this issue, not just "Bug" or "Crash".
- [x] I agree to follow Nextcloud's [Code of Conduct](https://nextcloud.com/contribute/code-of-conduct/).

### Steps to reproduce

1. Take photos with a poor internet connection (eg in a remote area)
2. Auto-uploads attempts to upload them
3. Internet momentarily drops out
4. Upload fails

### Expected behaviour

The upload should automatically retry once better internet is available.

### Actual behaviour

The image is never uploaded. Later images continue to upload normally, but I have about 50 images which haven't been uploaded despite being in a directory set to auto-upload. I have no option to retry these failed uploads, with the upload history only listing the successful uploads.

### Additional information

I love Nextcloud, but the auto-upload feature feels incredibly unreliable, and I am petrified that I will inadvertently lose data due to failed uploads. Some time needs to be spent hardening this feature to make it far more resilient to errors such as network failures.
