Move Upload File to Cloud logic to Vue

[farmaazon]

Pull Request Description

A prelude to #13491

Move upload file logic to Vue. It will be needed when handling hybrid projects.

Important Notes

Because of various problems with tanstack query we faced lately, which were hard to debug, I decided to not use it in the new implementation. I moved the "pooling" mechanism to the new store.

@somebody1234 I re-requested review, as I did a significant change:

1. Restored mutations, as they seem to be required for proper asset list refreshing
2. Added simplified logic for local file upload.
