Fix and improve POW dishwasher and washer configs

- Remove redundant interval block overriding status_led behavior
- Add UART id and reference it explicitly in cse7766
- Replace manual power factor template with native cse7766 power_factor sensor
- Remove redundant switch_led control from bi-stable relay actions
- Fix stray quote in energy sensor name (dishwasher)
