Allow Length of Task to Reflect on Task Calendar

Goal: Enhance the task calendar to accurately track the duration of maintenance on a property.

Current Issue: When a long-term maintenance task is entered (e.g., a 45-day pool closure), it currently appears as a single marker on the start date.

Requested Feature: Tasks should visually span the entire length of the maintenance period on the calendar (e.g., a 45-day block) to clearly show when the property (or a specific amenity) will be unavailable.
