Add account balance and amount due to sensor attributes

Extended WatercareUsageSensor to include 'account_balance', 'amount_due', and 'reading_type' in the sensor attributes. Also added 'usage_to_lower_band' for efficiency statistics. This provides more detailed billing and usage information in the sensor state.
