[feature] Use multicolor progress bar to show mass upgrade operations #349
Description
As discussed in the GSoC'25 weekly sync, we could improve the UX of the mass upgrade operations page by using a multicolor progress bar.
Currently, we only show a single-color progress bar, which works fine for a single upgrade operation. However, for mass upgrades it is not very informative. A multicolor bar would make it easier to quickly identify how many operations have:
- succeeded
- failed
- aborted
- been cancelled
This would serve as a summary of the entire mass upgrade operation and provide better visibility to users.
