E Chief SGH01 planter: naming changes, file disambiguation

- from manual link, "Dongguan E Chief" seems to be the manufacturer (assume the brand is without the city name prepended)
- avoid overriding default entity name where it is unnecessary
- follow HA case convention for names
- consistent use of "timer" rather than "countdown"
- readonly number entity should be a sensor
