Video File was marked as uploaded, but file size is much smaller / file corrupted

### ⚠️ 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. Setup Video auto upload
2. Make a video around 200+ MB
3. Upload will be triggered on a poor connection (upload speed 1,2 Mbps). 
5. See multiple retries and errors in NC Server logs
6. Finally file marked as uploaded
7. Check file on a server and it has totally different size: 34 MB, vs 200+ MB original file. 

### Expected behaviour

App can check if file was uploaded successfully even with network errors and retries. At least final File size must be compared, better is to implement checksum comparison such as SHA256

### Actual behaviour

There is no file size or any checksum comparison after upload, if file was corrupted, user will never know about this issue till he need this file...
