feat: DG430 V2.0.3 — 波动测试模式 前端+后端同步

edc_server:
  - dg430.py: 新增0xB4解析; 0x4C扩展6字段(向后兼容)
  - models.py: tb_fixture_param DDL + upsert 新增6字段
  - handlers.py: parse_loop 添加0xB4处理; 0x4C传参扩展

edc-web:
  - fixture.py: build_4b_packet() 新增6个波动参数
  - models.py: upsert_fixture_param 字段列表扩展
  - fixture.html: 新增波动测试参数输入区(6字段)
  - fixture.js: getFormParams/fillForm/saveToDb/sendConfig 全部扩展
