Handling missing data points while switching stats source

Related to switching data source to ohsomeNow stats, #5999

Can we please have - instead of 0 for POIS and waterways under My Contributions section? Also, possible to link to ohsomeNow about page - https://stats.now.ohsome.org/about as part of the tooltip message?

The linking of the ohsomeNow about page to the tooltip message is not possible with the current setup of our tooltip display since the tooltip fades away when the cursor moves away from the info icon. Due to this, the user cannot click on the hyperlink. In order to address this issue, we need to refactor the tooltip setup on the frontend, which would require some time and effort.

Sounds good @royallsilwallz - we can see how we provide that info later. As long as we handle the missing fields with a - we are good for the current release.
