fix(profiles): a stored <root>/profiles/<name> home names its profile even when the root carries no markers

CI: tests/test_tui_gateway_server.py::test_ensure_session_db_row_stamps_profile_name used a bare tmp
root; profile_name_for_home fell through to None and the row was stamped default. The stored home
is authoritative (its owner resolved it), so the profiles/<name> shape is sufficient.
