What is the service territory hierarchy and how is it used?

Service territories can be organized in a parent-child hierarchy to reflect real-world geographic or organizational structures (e.g., Region > District > City). The hierarchy is used for:

1. Dispatcher Console Filtering — dispatchers can view the Gantt for all resources within a parent territory and all its children.
2. Relocation Territories — a technician assigned as a member of a child territory can be designated as a "Relocation" member of the parent territory, allowing them to work in adjacent areas when needed.
3. Operating Hours Inheritance — child territories can inherit operating hours from the parent.
4. Optimization Scope — the optimizer can be scoped to a specific territory and all its children for focused regional optimization.
