Why?
OPT-6146 implements tracking of individual events, but doesn't track cumulative number of shared entities. If we had this information, we'd be able to correlate sharing with other overall behavior (upsell, pageviews, users per organization) to see its impact and validate that it's a high-value action.
This is not critical to OKR success, so should not interrupt existing work.

Scope:
Add the number of shared entities (shared dashboards and reports, preferably separately) to the Heartbeat job so we can track it
