Report User Login Statistics

### Current Behavior:
Dependency-Track v3.5.1 provides two screens that display user statistics: "LDAP Users" and "Managed Users". These screens provide useful information on (say) the count of the number of teams that each user belongs to. However, there is no information on login information. All that one can infer is that a user who is listed in ""LDAP Users" has succefully logged in at least once.

This is a problem when one has users whose job role requires that they make use of Dependency-Track. But you have no idea if they are actually doing so.

### Proposed Behavior:
Add sortable columns that would display:
* Total Login Count
* Last Login Timestamp
