ci: add DQN evaluation step and skip builds on CI-only changes

Add evaluate_baseline after DQN training smoke test so we get Sharpe,
MaxDD, WinRate, and ProfitFactor in the pipeline artifacts. Remove
.gitlab-ci.yml from changes: filters so CI-config-only pushes no longer
trigger the full check→test→compile→build pipeline (~20 min saved).
