Add Chigo air conditioner (jqfsu2e8pvpce5ra) (#5414)

* Add Chigo air conditioner (jqfsu2e8pvpce5ra)

Local config for a Chigo Wi-Fi air conditioner. DP map verified against the
Tuya cloud thing-model API (abilityId == DP id), including the turbo/swing/timer
datapoints that the standard instruction set hides.

* fix: use translation_key for Sleep switch and Timer number

CI's untranslated_entities check flagged that existing en.json
translations already cover "sleep" (switch) and "timer" (number),
so the explicit names should be replaced with translation_key
references instead.

* fix: address review feedback on Chigo air conditioner config

- Use generic top-level name so other products can share this file
- Split product name into manufacturer/model (FCH-12-UI-UE)
- Move horizontal/vertical swing from standalone switches to the
  climate entity's swing_horizontal_mode/swing_mode attributes
