test: add missing coverage for web UI, Jira extract, instance config, and concurrent rebuild

- tests/test_web_ui.py: smoke tests for all authenticated web pages (login, dashboard, catalog, corporate-memory, activity-center, admin/tables, admin/permissions)
- tests/test_jira_service.py: unit tests for extract_init and update_meta in the Jira connector
- tests/test_instance_config.py: verifies get_instance_name() returns a string when config file is absent
- tests/test_orchestrator.py: concurrent rebuild test asserting rebuild succeeds while a read-only connection holds the analytics DB
