Add config parameter for core-database to allow using real counts

[air1one]

In core-database package add a config parameter to use real counts instead of estimates (default it to not using real counts in defaults.ts)

This is quite risky and could easily be abused on lower-spec nodes because the estimates were implemented specifically to let the node maintainer decide based on their specs if they can handle them or not. If we allow them to be disabled via query parameters there is no point in having them at all.

Ok so after talking about it, the config parameter will be enough @rainydio no need for URL param, the node maintainer decides either to allow real counts for every request or estimates for every request.

This simply needs to be ported to 3.0 by using the estimateTotalCount configuration from the core-database package.

Implemented in #3725
