Optimize of Activity feed and Contact search query

[lojsk]

On Contact search, we get rid of additional queries for triggers and emails, and is now done with joins. Also, we return already greatest createdAt and sort by it on the query level.

For Avtivity Feed, we do limits and offset already on the DB level, that way queries become way faster because they don't need to get all the data from the DB to the backend. To get the same format, we used to_jsonb and jsonb_build_object. For bringing triggers and emails to the same table we used UNION, for that reason, all can be done in the DB level, even pagination.

Extra small fix is filtered.length to contacts.count, where I think that the correct value that should be used.

The JOIN condition is incorrect. It should be e."contactId" = c.id instead of e.id = e."contactId". The current condition joins emails table on itself rather than joining it with contacts.

Suggested change

	LEFT JOIN emails e on e.id = e."contactId"
	LEFT JOIN emails e on e."contactId" = c.id
