Reflect in UI that Application Statistics in Admin Area can show approximate data for values more than 10,000
Problem to solve
Currently, the statistics section in Admin Area > Dashboard > Instance overview uses Get current application statistics API to get the data, and it might show approximate data according to the note from the docs. It is because we use different strategies to calculate values. For values less than 10k we use exact counts, but for values more than 10k we use ReltuplesCountStrategy and TablesampleCountStrategy:

- https://gitlab.com/gitlab-org/gitlab/-/blob/v16.7.0-ee/lib/gitlab/database/count/reltuples_count_strategy.rb?ref_type=tags
- https://gitlab.com/gitlab-org/gitlab/-/blob/v16.7.0-ee/lib/gitlab/database/count/tablesample_count_strategy.rb?ref_type=tags
