ci: add coverage summary printed to job log

Adds a step after backend coverage that parses the JaCoCo XML report
and prints a formatted table showing line and branch coverage with
pass/fail status against thresholds (70% lines, 60% branches).

The frontend coverage is already visible from Vitest's built-in text
reporter which prints during npm run test:coverage.

Both HTML reports remain downloadable as artifacts (backend-coverage
and frontend-coverage ZIPs).

Result: coverage numbers are visible at a glance in the CI job log
without needing to download and unzip artifacts.
