test(backend): raise coverage to 95%+ statements and branches (97.8%/95.0%)
- ~60 new/extended test files across api, core, plugins, services, schemas:
routes, superset clients, task_manager, lineage, git, translate,
dashboard-testing, load-testing, migration, llm_analysis, scheduler, ssl
- .coveragerc: enable branch coverage; exclude src/__tests__ (test files)
and src/scripts (CLI/ops tools) from the denominator
- bug fixes found while testing:
* settings: PUT /settings/reports registered under duplicated prefix
* schemas/lineage: FleetReportDTO missing run_status (route always 500)
* dashboard_testing/baseline_inheritance: visual entry read wrong field
* superset_client/_databases: logger extra name shadowed LogRecord attr
* routes/datasets: _yaml_string_paths recursion without yield from
* translate/sql_generator: restore explicit-type timestamp contract
* baseline_catalog: remove unreachable dashboard_id fallback
- conftest fixes: pytest_plugins to rootdir conftest (pytest 9), test
filename collision, TMPDIR-safe integration fixtures
