Bug: container memory usage show as 0B on ARM (RPI 4)

Bug Description

debug-arcane_agent_rpi4.log

In my use case i have a Raspberry PI 4 where i've installed arane agent (arcane-headless image)

When i go to Ressources / Containers to show memory usage for each container, value is showed to 0B in place of real memory usage value it's happening only for mi RPI 4 (ARM).

The issue affect also Container / metrics (stats) page, all values for memory are set to 0.

Steps To Reproduce

1. Select an RPI4 (ARM) environment
2. Go to Resources / Container
3. Look into "Memory usage" for containers (all set to 0B)
4. Click on one container
5. Go to Metrics tab
6. Look into "Memory usage"

Expected Behavior

I expect to see real memory usage for each container

Actual Behavior

Instead of having memory usage on B / KB / MB / GB we only see 0B. It's seems that arcane has issue to get memory information on ARM architectures
