refactor: move charge port and valet to switches, add exists_fn

Per review feedback on Hyundai-Kia-Connect#1647:
- Charge port: replace open/close buttons with single switch
  (value_fn=ev_charge_port_door_is_open, on=open, off=close)
- Valet mode: add as switch (value_fn=valet_mode_active)
  instead of start/stop buttons
- Windows (open/close/vent): keep as buttons — 3-state
  (closed/vent/open) doesn't fit switch on/off
- Hazard lights: keep as buttons (fire-and-forget, no state)
- Add exists_fn to HyundaiKiaButtonDescription, remove hardcoded
  if-else checks from async_setup_entry
- Remove charge port and valet button translations, add switch ones
