ci: run unit tests only, disable verbose output and logging overhead

On 2-core ARM runner, 2893 tests with verbose output and live log
capture take 2.5h+. Major bottlenecks:
- Coverage: disabled (previous commit)
- Verbose output (-v): generates huge I/O over Docker bridge
- Live log capture: logs every HTTP request per test
- Integration tests: heavy DB fixture setup (~7s each)

Now: unit tests only (2484), quiet mode (-q), no log capture,
LOG_LEVEL=WARNING. Integration tests run locally via make test.
