[F2V] Show storage almost full and full warning

[skjnldsv]

Closes #25293
Closes #26518

Just a temporary showWarning and showError is fine I guess. It will be displayed for a short amount of time, but closable
I would add this to the Quota Component, and maybe a watcher so that if there is a change, we show the warning again (only if it wasn't warned before)
