Add support for Junsun EV Charger (#4188)

* Add support for Junsun EV Charger

This EV Charger supports charging current adjustment mid-charging without disconnecting.

* Increase max current range to 32A

* feat (junsun_ev_charger): naming standardization

- use "Charging mode" as other chargers do rather than the ambiguous "Working mode" from Tuya naming
- since there is only one phase, remove the "Phase A" names and let standard translations be used.
