Update to the /unit_calendars endpoint to resolve an issue where calendars were being returned incorrectly when a rate set was not configured, or when the endpoint attempted to apply fallback automatically.
- The calendar response now reflects the actual end of the configured rate set:
  - If there is a break in the rate set within the requested time span, the calendar will end at the break.
  - If the rate set is continuous but ends before the requested end date, the calendar will return only up to the last configured date in the rate set.
Update to the /unit_calendars endpoint to support the fallback_rates parameter. When enabled, this parameter creates a fallback rate set that extends the calendar view beyond explicitly configured rates.
- Note: The calendar is designed to show absolute availability. To distinguish between standard configured rates and fallback coverage, compare responses with and without the fallback_rates parameter enabled to identify which dates are being filled by fallback.
