Pull request overview

Adds support for Home Assistant Core’s new in_zones field in update_location webhook payloads when the app is configured to send zone-only location updates, gated by Core version support.

Changes:

• Add in_zones to WebhookUpdateLocation and populate it for zone-only location updates when supported by Core.
• Introduce RLMZone.zones(of:in:includingPassive:) to return all matching zones (sorted by radius) and use it when building zone-only updates.
• Extend unit tests for the new in_zones payload and the new multi-zone lookup behavior.
