[Feature Request] Add "Update All" button for containers

[alz3abi]

Currently, when multiple container updates are available, users must click "Update" on each container individually. This becomes tedious when several containers need updating simultaneously.
Feature Request:
Add an "Update All" button that allows users to update all containers with pending updates in a single action.

• Current Behavior: Each container must be updated individually

• Proposed Behavior: Add an "Update All" button near the ZimaOS update notification or at the top of the container list

Optionally show a confirmation dialog listing all containers that will be updated
Update containers sequentially or in parallel with progress indication

Benefits:

• Saves time when multiple updates are available
• Improves user experience

Use Watchtower. I lasted years without ever updating a container

I’m using it without any issues, but it would be very helpful to add an “update all” button.
