feat: add CI/CD testing infrastructure with test.sh orchestrator

Complete testing system: pyproject.toml (pytest markers), test.sh
orchestrator with auto app start/stop and colorful summary,
pre-push hook, Gitea Actions workflow.

New QA tests: API health (7 endpoints), responsive (3 viewports),
log monitoring (ERROR/ORA-/Traceback detection), real GoMag sync,
PL/SQL package validation, smoke prod (read-only).

Converted test_app_basic.py and test_integration.py to pytest.
Added pytestmark to all existing tests (unit/e2e/oracle).
E2E conftest upgraded: console error collector, screenshot on
failure, auto-detect live app on :5003.

Usage: ./test.sh ci (30s) | ./test.sh full (2-3min)
