fix(translations): resolve hassfest selector key validation errors

Changed all selector option keys from uppercase to lowercase to comply
with Home Assistant's hassfest validation pattern [a-z0-9-_]+.

Fixed inconsistency in PEAK_PRICE_MIN_LEVEL_OPTIONS where some values
were uppercase while others were lowercase.

Changes:
- translations/*.json: All selector keys now lowercase (volatility, price_level)
- const.py: Added .lower() to all PEAK_PRICE_MIN_LEVEL_OPTIONS values
- binary_sensor.py: Added .upper() conversion when looking up price levels
  in PRICE_LEVEL_MAPPING to handle lowercase config values

Impact: Config flow now works correctly with translated selector options.
Hassfest validation passes without selector key errors.
