test: address PR review — shared fixtures, coverage, hygiene

Extract Flask client fixtures to tests/conftest.py, use client_single
for search limit tests, and relax session count assertion to >= 1.
Include utils/ in coverage (omit untested export modules), stop
tracking .coverage, and align integration-tests CI with full cov scope.
