fix (confortotal_minisplit): fix temperature range, and F mappings

- Use the Celsius range rather than full range for the dp, so HA shows the range correctly.
- mark Fahrenheit mappings as hidden so they are not used in reverse.
- Round Fahrenheit mappings to 0.5C increments

This should improve the behaviour of the climate entity, and avoid strange behaviour of
switching between F and C on the device display due to some temperatures reverse mapping
