Show more useful stats in dashboard

[Zodiac1978]

Describe the bug
At the moment we have two possible stats that could be activated to show up in the dashboard:

https://antispambee.pluginkollektiv.org/documentation/#spam-counter-on-the-dashboard
and
https://antispambee.pluginkollektiv.org/documentation/#statistics-on-the-dashboard

We have very low questions in the support forums, but one topic that arises regularly is the mismatch between the stats and the actual amount of spam.

Example No. 1:
The dashboard is showing 30 spam comments for today, but the spam table is showing less spam comments because
https://antispambee.pluginkollektiv.org/documentation/#delete-comments-by-spam-reasons
is activated and some of the comments are deleted immediately and therefore creating a mismtach.

Example No. 2:
The dashboard widget is showing 10 spam comments per day (now is friday) and the option
https://antispambee.pluginkollektiv.org/documentation/#delete-existing-spam-after-x-days
is activated and set to 3 days. The resulting amount of spam is not matching the sum of the widget.

Example No. 3:
The "At a glance" widget is showing the overall amount of spam, not the actual spam. Especially if spam was deleted manually or because of example 1 or 2.
Although it was a useful link, we removed the link to the spam comments table because it was too confusing for the people. Especially because it was not documented clearly in the widget (for example via hover info).

How could this be fixed?

1. Maybe we could add more stats under or in the graph:
   Overall spam blocked: xxx
   Spam today/week/month: xxx
   Directly deleted (if this option is enabled): xxx (as a 2nd line?)
   Current: xxx (this could be a link to the spam comments, so that power user can now click an d check for false positives)

2a. Or we remove those stats completely, because these are mostly making no sense at all:
Showing stats without any actionable item does not make much sense to me.

2b. We could add the link to edit-comments.php?comment_status=spam back, but with a better link text. Show spam count? or with a call to action like "Check for false positives" - This would save one click ...

Maybe it would be enough as a first fix to add a small description to the graph what is displayed there (that those numbers can differ from the spam count in the comments view) and clarify the text for total blocked comments

One more problem:

• For today the graph shows 121 spam comments.
• I've enabled notifications
• I've got only 3 spam comment mails sent to me

What is happening here? Counter to high? Lost rejected comments?
