fix: remove broken CI coverage infrastructure

The coverage collection had multiple issues:
- Wrong pytest markers caused 0 tests to run
- Postgres jobs silently skipped artifact uploads
- Coverage Summary job failed when artifacts were missing
- uv venv picked wrong Python version for coverage jobs

Simplify: every job just runs tests via `just` recipes. No more
dual code paths, artifact uploads, or summary aggregation job.
