fix: report line-only coverage honestly and tighten Bun test helpers

The generated HTML and Cobertura reports no longer show unmeasured
branch and function coverage as 100%. Poll and waitFor deadlines use
performance.now so frozen dates cannot make them loop forever, the
malformed-configuration test covers undefined again next to the empty
array, compose health checks honor PORT, and the migration spec lists
only what is still open.
