feat(db): 新增线圈参数表/模拟车辆参数表 + tb_fixture_param/tb_state_tst 关联字段

- CREATE TABLE tb_coil_info (线圈编号/名称/电感量/形状/尺寸/圈数/电阻/材质/备注)
- CREATE TABLE tb_simulate_car (模拟编号/名称/形状/尺寸/材质/备注)
- ALTER TABLE tb_fixture_param ADD coil_id, simulate_car_id
- ALTER TABLE tb_state_tst ADD coil_id, simulate_car_id
- 新增 get_fixture_coil_car_ids() 查询当前关联
- insert_test_result/insert_wave_data 自动从 fixture 获取线圈/车辆并记录
