feat: badges backend

[gaspergrom]

Note

Introduces a total rows count for each leaderboard snapshot and surfaces it in query results.

• Extends leaderboards_copy_ds schema with totalCount and updates leaderboards.pipe to select it
• Updates all copy pipes (commits, stars, forks, package-downloads, codebase-size, avg-commits-per-author, small-teams-massive-output, fastest-mergers, fastest-responders, resolution-rate, active-contributors, active-organizations, contributors, organizations) to compute count() OVER () as totalCount and write it to the datasource

Misleading totalCount for limited leaderboards

Medium Severity

The count() OVER () window function computes before LIMIT 100 is applied, so totalCount reflects the full count (potentially thousands) while only 100 rows are actually stored. API consumers querying the contributors or organizations leaderboards will see a totalCount suggesting thousands of pageable items, but attempting to paginate beyond the first 100 rows will return empty results.
