[Bug][UI] Quota fill bar doesn't seem to fill the area available even when well above quota

[ericlinagora]

Describe the bug
Note that these screenshots are based on uploading files with a version of the backend that did not include the quota checks. The bug is the display of the bar only, not the actual over-quota.

Expected behavior
The bar should at least be completely filled. Possibly choose whether to handle over quota situations, they might happen in normal use too if for ex. a quota is reduced. If we do, it might be worth having a warning message, possibly even deactivating upload buttons/areas/etc.

Note

Could be worth combining work with issue #475
