Visual appearance of quota message should not look like an error / Don't show warning for no quota

Is your feature request related to a problem? Please describe.

Inside the Mail app the icon for the quota information is an exclamation mark. This appears like a warning message for the inexperienced users, even if there is no problem at all. (For example, if only 1% of the quota are already used.

Secondly, if the server does not support quota at all, because the server does not care for quota, the message reads as if something was wrong. Also, if the server reports 0 as the quota limit (which means "unlimited"), the message tells the user that the servers fails to support quotas even though this actually is a good thing for the user.

Describe the solution you'd like

Please make the message less infringing.

For example, use a little storage icon (e.g. a disc symbol, a "database" symbol) or anything else which does not look like an error symbol unless there is a real warning or error.

In case the server does not support quota at all or reports an unlimited quota do not show any message or at least change the wording to something which does not sound like there was an error.

The issue does not name a file, test, or entry point; begin by locating the Mail app's quota display and related UI tests. Done means quota information no longer appears as an error when usage is low, unsupported, or unlimited, while genuine warnings remain distinguishable.
